Most Important Guide Ever – Olympic Collars Guide

Olympic collar buying guide

Well maybe Olympic collars aren’t the most important piece of equipment ever, but I didn’t want a boring title for a kinda boring article. =)

This is a simple guide to pretty much all of your Olympic collar options, and there are many! Other than to mention that I cover both the basic 50 mm (~2″) collars and professional, weighted Olympic collars (no 1″ collars covered), this guide really doesn’t need much of an introduction.

Classic Spring Collars

Basic Spring Collars from Rogue Fitness. $9.50!

Your basic, no-frills 2″ spring collars – about $9

We have all owned these; probably still do. They mostly work, and they just scream “I’m cheap!” Over time they’ll stop holding on to the bar so well; especially if you leave them on the bar in-between workouts, but for around $9 you can replace these over and over.

Other than being inexpensive, there aren’t many advantages to spring collars. They have no substantial weight to them, youth and women lifters with small hands commonly have a hard time getting them on and off the bar, and they don’t work on most specialty bars. To be fair, they do hold pretty well when they’re new though, especially if your bar has grooved sleeves. Just make sure you open them up as much as possible to avoid taking the zinc or chrome coating off your bar.

Cheaper than Cheap – Spring Clamps

spring-clamps-cheap

 

If spring collars aren’t quite cheap enough for you, look for a pair of these 2″ spring clamps in your garage. They’ll work, so long as you don’t drop the bar. Then again, maybe they won’t. I haven’t tried; I own collars.

Lockjaw Pro Collars / HG Collars

Rogue HG Collars - Lockjaws

Rogue Standard HG Collars / Lockjaw Collars – Approx $39 a pair.

Lockjaw Collars are probably the most common alternative to spring collars. They’re a lot easier to use, lock on to the bar more securely (and stay locked when dropped), and they won’t scratch up your bar sleeves. They also fit some specialty bars that spring collars will not, although it’s not a very tight fight. You can pick these up for about $40 just about anywhere.

Be careful if you buy these from someplace like Amazon that also sells Standard barbell equipment (1″ rather than 2″), as these are available for both size sleeves, and they look almost identical at a quick glance. Don’t buy the wrong set.

Rogue Metal HG Olympic Collars

Rogue Metal HG Olympic Collars – $49.50 a pair.

Alternatively, Rogue also has Metal HG Collars as well. The collars themselves are metal, but they are still coated in plastic; presumably so they don’t scratch up bars. They don’t say how much they weigh, which is kind of lame, but the few reviews that there are so far say they perform well. Not sure if I see a reason to go metal over standard HG/Lockjaw collars, but the option is there. $49.50 a pair.

Muscle Clamps

Muscle Clamp Collars on Rogue Bar

Muscle Clamp collars are incredibly easy to use, but are not ideal for repeated drops.

Muscle Clamps are great collars, in the right setting. They are extremely easy to use, they don’t scratch up the bar sleeves, and they hold very well. Where you wouldn’t want to use them is when you do a lot of bar ditching. These are not the best collars for clean & jerk and snatch training; they will pop open (not that Olympic lifters train with collars anyway!)

You’ll commonly find Muscle Clamps in commercial gyms because of how reliable and simple to use they are in that kind of setting. Since you can’t normally drop loaded barbells in most globo-gyms, their Oly weakness is never really exposed. I have these collars and I like them a lot, but I keep them in the rack for benches, squats, etc. $38 from Rogue, black only. Red and Blue can be found on Amazon.

Proloc Collars

Rogue Proloc Collars and Proloc 2 Collars

Proloc Collars (left) and Proloc 2 Collars with carabiner for chains.

Proloc Collars are awesome. These will hold on to extreme weights better than spring collars will, and for years longer! They are simple to use and they are much more likely to fit specialty bars like logs, Swiss bars, cambered bars, and so forth (range of 1.937″ – 2.007″). Proloc collars are available in black or red – $39. You can also find some other random colors on Amazon.

Then there is the Proloc 2 Collars that come with a 5/8″ carabiner on each collar for hanging chains. Same easy and solid lock down, but now with the ability to easily and quickly add the chains – $59.

OSO Barbell Collars

OSO Barbell Collars

OSO Barbell Collars, in many colors! $49.95

Probably the coolest looking collars, the OSO collars come in a variety of metallic colors, and work much like Lockjaws in the way they attach to the bar. The word is that they can withstand lots of dropping without coming loose, but I can’t speak to that as I have yet to come across these things. For not much more than Muscle Clamps or Lockjaws, you can have  a cool looking metallic cog for a collar!

Rogue Metal Axle Collars for Specialty Bars

Rogue Metal HG Collars for 1.9" specialty bars

Rogue Metal HG Collars being used on Rogue Farmer’s Handles

Metal Axle Collars are Rogue’s answer to collars for specialty bars like the farmer’s handles, Swiss bars, axles, and other bars that have 1.9″ (48.3 mm) bar sleeves. Axle collars will hold tight on these specialty bars, but they will not work on standard 2″ (50.4 mm) barbells.

These work exactly like the Rogue HG Collars/Lockjaw Pro Collars. They are $49.50 a pair, red only. Again, these will not work on your standard Olympic barbell.

Strongman Pipe Collars for Specialty Bars

Raw pipe Strongman collars

Steel pipe Strongman collars. The pair on the left is from Black Widow ($30) and the pair on the right is Elite ($50).

Depending on where you get these, they can be a cheaper alternative to Rogue’s Axle Collars for your specialty bars. These collars are literally pieces of steel pipe with a large bolt welded over a hole so that you can tighten down a screw into your bar sleeve. I wouldn’t recommend these for any bar that has a zinc, chrome, or any other finish that you care about, because these will scratch your bar up good. I do use the Black Widow collars for farmer handles, but I sure wouldn’t put them anywhere near a real Olympic bar.

I suggest you take the price of these ($30-50/pair) and apply that to some Axle Collars or Proloc collars. Either of which are much easier to use anyway. Just my 2 cents.

Strap Barbell Collars

Strap Barbell Collars

Strap Barbell Collars fit any diameter bar sleeve, but don’t really hold much better than spring collars.

Little disclaimer, I’ve never used these, nor would I if I had to buy them myself. I wanted to include them though, so I dug and dug until I found a fair amount of user feedback.

The word is this: Strap collars work, but are not much of an improvement over spring collars, if any at all. The only clear advantages to strap collars is that they travel easy (if you still lift at a gym that has shitty collars, and need to bring your own), and that they technically fit any size bar sleeve.

Like I said, I’ve not used these personally, but the feedback I kept running into was pretty consistent; you can do better for the money. So for the $20-$30 price tag, you may as well just buy Lockjaw or Muscle Clamps.

♦ ♦ ♦

Weighted / Competition Collars

Let’s talk about real collars. That is, collars that have some weight to them. They’ll cost more, but they do allow you to know exactly what weight you’re lifting, they hold strong to the bar, and most of them look so much cooler on your fancy bar.

A Warning about Collar and Bar Sizing

If you have a lower end barbell; something you found at Academy, Dicks, Amazon, etc for like $100 or less (CAP, Gold’s, Body Solid, Troy, and so forth), be warned that these higher-end competition collars may not fit your bar.

IWF-standard barbells have sleeves that fall between 49.5 mm and 50 mm in diameter (1.949 inches – 1.969 inches.) The insert, or opening of competition collars fall between 50.2 mm and 50.8 mm (1.976 inches – 2.0 inches). Cheap box-store bars that are advertised as 2″ Olympic Barbells would already be too big for most calibrated equipment even at exactly 2″, but because they aren’t manufactured to very strict tolerances, they can be even thicker.

Don’t buy competition collars, competition bumpers, or change/friction plates if you own a cheap, 2″ box-store bar. Stick with spring collars, Lockjaw collars, or Muscle Clamps. Or rather, buy a real bar. It’s really not the piece of equipment to be cheap on! (not that anyone with a $100 bar is going to buy $200 collars, but better safe than sorry!)

Ivanko Chrome 2.5 Kilo and 2.5 Pound Collars

Ivanko Chrome plated iron collars

Ivanko Chrome 2.5 kg Collars (left) and Ivanko Chrome 2.5 lb Collars (right).

Ivanko offers professional weighted collars in both pounds and kilograms, which is pretty cool. Most of the weighted competition collars are going to be in kilos, so it’s nice that guys who lift in pounds can get real collars too. Ivanko collars are not IWF-approved.

The Ivanko Kilo Pressure Collars are cast iron collars calibrated to fit any IWF-standard Olympic barbell. Each collar weights 2.5 kg and has a nickel base applied before it is triple chromed. Beautiful collars – $136

The Ivanko Chrome Training Collars are similar to the above kilo collars, but rather than kilos they are 2.5 pounds per collar. They look a little different but they are effectively the same thing. These are also very good looking collars – $69

Bulldog Olympic Collars – 2.5-pound set

Bulldog Aluminum Olympic Collars

Bulldog Aluminum Olympic Collars – 1¼-pound per collar.

I’ve heard mixed feedback on Bulldog Collars. They’ve got a very nice aluminum body and steel hardware, and they look pretty cool, but word is they don’t stay locked down very well, and require constant tightening. At $60 a pair, that’s not really what you want to hear. I also don’t think I’d want a set of collars that weighed 1¼-pounds each; it seems like an overly complicated number to have to work with. Finally, although these look as though they may fit specialty bars, they will not.

In any case, this is another brand that global gyms will use, so if you have experience with them and like them, by all means get yourself a pair. Bulldog collars have a five year warranty.

Eleiko IWF-Approved 2.5 kg Competition Collars

Eleiko 5 kg pair Competition Collars

The Eleiko IWF-approved Competition Collars – 2.5 kg per collar.

Now we’re getting into the real collars. The Eleiko Competition collars are IWF-approved, chrome plated collars that weight 2.5 kg per collar. These are intended to allow quick loading and unloading of plates. These are chrome plated, have a thinner profile to allow more weight on the bar, and they have a foldable handle so that change plates can be loaded outside of the collars. Are you ready for this? $289 per pair and a 2-year warranty.

Fortunately, Eleiko also makes training versions of these collars that are not IWF-certified, but still offer the same function and weight. Training collars can also be purchased in pounds. Eleiko even makes Powerlifting training collars. All non-certified Eleiko Training Collars are $129.

Uesaka Sevi IWF-Approved 2.5 kg Competition Collars

Uesaka IWF Approved Sevi Comp Collars

Uesaka IWF-approved Sevi Competition Collars – 2.5 kg per collar.

If you were going to buy Eleiko Comp Collars but found you were $6 short, try these! The Uesaka Sevi Collars are only $283 and they too have a very unique look to them. Just like the Eleiko’s, these are IWF-approved and weigh exactly 2.5 kilograms per collar. They are finished in hard, shiny chrome and create an air-tight lock on the bar. They are also backed by a 5-year warranty, which is 3-years longer than the Eleiko’s; making these a pretty good deal by comparison. Pretty sweet collars.

Other IWF Competition/Training Collars

Other competition collars

There are many IWF-certified competition and training collars.

Every IWF and IPF-certified barbell manufacturer has 2.5 kilogram collars; some are even magnetic! The Eleiko’s and Uesaka’s from above aren’t even the most expensive. If you want DHS, Leoko, ZKC, or WerkSan collars to match your bar, you can grab those from the manufacturer. Expect to pay $200-300+.

Ader Chain Collar Sets

Ader Chain Collar Sets

Ader Weightlifting Chain Collar Sets in Zinc or Black Oxide – 3 pairs (6 collars) per set – $300 for full set.

It is generally slightly less expensive to buy chain-ready collars like the Proloc collars, and then hit up the hardware store or Tractor Supply Co for your chains, but for some, buying something like these pre-assembled chain collars in sets is just so easy it’s worth the few extra bucks. As you can see in the picture, this Ader set includes 3 pairs of chains (2 pairs of each weight) and can be purchased with either a zinc protective coating or black oxide coating.

Each chain is 5′ long so you should have no problem with them piling up on the floor at the bottom of your lift (as they should.) The beauty of these is that you don’t have to swap out chains on collars; each chain has its own collar already. For the zinc set, go here. For the black oxide set, go here. You can also buy these in just pairs of whatever weight you prefer; a quick search on Amazon will reveal all the individual listings. Pretty cool.

The downside of these over the Proloc and your own chains is that you can only get so many plates and so many chain collars on the sleeve.

MostFit Syn Rings

MostFit Syn Rings

MostFit Syn Rings for hanging plates/kettlebells.

They aren’t really collars in the normal sense. I saw these some time ago and thought they were a creative alternative to hanging kettlebells with resistance bands. I’m not sure how beneficial suspending weights from a bar actually is, but I’d imagine the instability does help to improve stabilizer muscles to some degree. Syn Rings are only about $40 and they can be found on Amazon or random fitness retailers.

Olympic Collar Summary

I found a few other random collars out there, but they were all more or less the same as one of the above collars with minor cosmetic differences, or just different brands of the same thing. If you can’t find something you like in this list, you’re probably just hard to please!

My recommendation?

I think for most people’s purposes, either the Lockjaw/HG or the Muscle Clamps will be perfect. Remember, avoid the Muscle Clamps if you Olympic lift and miss a lot. =P

If you prefer professional 2.5 kg collars, for personal use just go with Ivanko. If you need collars for an event, you’ll probably be required to use one of the IWF-approved brands like Eleiko or Uesaka.

You don’t have many choices for specialty bars, but of those options I prefer the Rogue Axles. Prolocs are fine, I just don’t personally like turning knobs and screws.

    Little feedback on the OSO. Literally the greatest collar I have ever used. these hold almost as well as a compression Comp collar. They hold worlds snugger than any spring, clamp, Jaws, etc. Especially if you are doing a crossfit style multi overhead drop work outs. I personally dropped 100KG’s 30 times from over head and never had to tighten the weight! Plus compared the Lock Jaw, my wife loves them, because the long latch is much easier to release than the red button on the Lock Jaw.

    • jburgeson March 11, 2015, 3:49 pm

      Awesome to hear, thank you. I’ve actually got them on my list of ‘to try’ things. I do wish they were weighted tho

  • chris smith March 15, 2015, 2:29 pm

    Little feedback on the OSO collars. There are 2 sets floating around the gym that only get used by people that Oly lift and not crossfit. One set is still holding its tightness but one is starting to fail. We lined the inside of the collar with white lifting tape to get some of the tightness back but its finicky. Still a great collar though and I hope the set that is still going strong holds up.

    Personally im looking at the Vulcan collars. They seem like a very nice collar for the money.

    On a side note, after reading your Oly bar review, I ended up getting the Vaughn bar. Man what a great bar for the money. I do see the Vulcan Oly bearing bar in my future though ;)

    • jburgeson March 15, 2015, 3:12 pm

      Thanks for the feedback Chris. Glad you like that Vaughn. I have the Vulcan Elite as of Friday; the bushing variation of the Pro bar, and so far it’s looking like a pretty damn nice bar. It’s also a very attractive bar. The entire sleeve looks great, from the chrome to the dark end caps. Very excited to test that one out tomorrow.

  • Devin April 15, 2015, 8:46 pm

    I was wondering about the comp collars… do you actually have them, or were you just posting info about them? Based on your recommendations, I bought an American Barbell and love it. However, they now longer sell their comp collars. I bought a set from Fringe Sports and they didn’t it. Just wondering if you could measure the inner diameter or test them on your American BB bar?

    • jburgeson April 15, 2015, 9:32 pm

      Wait sorry, I’m confused. You bought an AB bar? or the collars? I see the collars on the website now, maybe they were sold out for a while? Your comment about the Fringe collars is missing a word, but I assume the missing word is fit. Which bar are they not fitting on, and which collars specifically from Fringe? The Vaughn?

      • Devin April 15, 2015, 9:40 pm

        Sorry… writing a few reports right now and I guess they received the grammar proofing. I bought an AB stainless barbell. It’s superb. I bought collars from Vaughn/Fringe and they didn’t fit. Sorry for the typo and confusion. I do see now that AB has collars back in stock. I was told by one of the reps for AB that the collars were discontinued and they were figuring out a different design. I guess that’s no longer the case.

        Sorry for the confusion.

        • jburgeson April 15, 2015, 9:50 pm

          Ah ok I got it, no worries. You wouldn’t believe how much I have to edit before I hit publish on anything.

          So ok, the high-end American Barbell bars have that extra layer of hard chrome, but that shouldn’t prevent the Vaughn collars from fitting. If you were going to have issues because of the extra thickness, you wouldn’t be getting your bumpers on that bar either, and I’m assuming you’re not having an issue with your plates.

          I’ve never seen the Vaughn collars so I don’t know how well they are built or to what tolerances they are made. I’ve had numerous collars on my AB SS including pretty much all of the household non-comp collars (lockjaw, M-clamps, etc), DHS comp collars, and an unknown pair that had the handle like the AB/Eleikos. They are snug, but it wasn’t a problem getting anything on. I didn’t even notice the extra thickness until I put the calipers to the sleeve while reviewing it.

          Do you have any issues clamping down other collars? If not, I’d probably return those Vaughns and order the AB collars since they appear to have them again.

  • Sandarpan April 17, 2015, 11:34 pm

    Hello,
    Have you ever seen one of these used as a collar? http://www.lighting-effect.com/images/Mini360QRClosedWeb.jpg
    I hear (repeat HEAR) good things about them all the time. It’s a 2 inch pipe quick release clamp. There’s a ton of variety if you look around. Pretty forgiving about the sleeve diameter variation. Looks similar to how a Lockjaw works. Retails for around $ 9. Here’s the product link

    http://www.lighting-effect.com/product_info.php?manufacturers_id=7&products_id=3792&osCsid=g84etdgrf4f0o9jltiispq7026

    Tell me what you think.

    • jburgeson April 18, 2015, 12:31 am

      I’ve never seen that before. I mean, it certainly looks like it would work, but it also looks like it could scratch at the finish if you’re not careful. Then again, many people don’t care about that kind of thing.

      • Sandarpan April 18, 2015, 1:17 am

        There are plastic ones too. Heavy duty plastic. And one more thing. When these are used on pipes (their intended application), I’ve always seen the inner surface of these clamps coated with some kind of rubber; not to avoid scratching the pipes but probably serves to seal the joint. That could probably help to not scratch the sleeve finish.

  • nated April 26, 2015, 9:03 pm

    For Ivanko, you missed the COT-1.25. It’s a compression collar like the 2.5 lbs chrome you have, except 1.25 lbs per collar.

  • Carl June 1, 2015, 5:15 am

    Another drawback of spring collars is that they are longer than 5&10 pound Olympic plates. So if you’re bringing small diameter plates from the floor, when you go to put the bar down it can actually end up resting on the spring clips. Not a problem with large diameter plates.

    • Joonas March 4, 2016, 1:27 pm

      I’ve noticed that too, but Eleiko actually makes spring collars where the handle end is bent 90 degrees, so they work with <5kg olympic/change plates as well. We have them at my gym, and while they're nothing to write home about as such, they're nice for accessory work for that exact reason.

  • Steven Ward July 16, 2015, 2:49 pm

    I promote the OSO product direction, as well as Werksan and Eleiko for the upper end. OSO has a growing line up to address the many use options but have found them to be tite on WOD workouts. There are piles of old lockjaws that pop open or slip in most boxes. Seem to work initially but soon loosen up, red lock button or not. Hi Temp has a unique rubber one but as yet, have not used it, but will be checking it out. Good article and site, BTW. Great information always !

  • Jeremy September 27, 2015, 12:44 pm

    Got an opinion on MDUSA’s heavy duty weightlifiting chain collars?
    They look strong, but would they scratch the chrome on my bar sleeves?
    Or would the nylon Proloc 2’s be safer?

    Thanks.

    • jburgeson September 27, 2015, 3:08 pm

      Prolocs would be better for the bar, yes. Any of the 2″ pipe collars like those MD collars have a bolt that runs through the threading right into the bar itself. I’ve actually got some of those pipe collars and I only ever used them on farmers handles; never on a real bar.

      • Jeremy September 28, 2015, 10:10 pm

        Thanks for the reply. I’m a beginner at weightlifting. I just ordered a AB SS WOD bar and a set of Troy PO plates. Next on my list is a power rack although I do have an old box store bench press rack which feels kind of small and flimsy but which might do for a while till I decide what I need and am willing to spend.

        I was considering the Proloc 2 for the chain clamp but decided that feature was unnecessary — I can always just hang a smaller chain through a rubber tube/hose to protect the sleeve finish.

        So then I almost pulled the trigger on the new $63 OSO Elites, but wasn’t sure how long the thin aluminum would last before metal fatigue set in from repeated clamping.

        In the end I decided to go with the tried and true chrome plated steel Ivanko COT-1.25 @ $60.50 + $9.75 shipping from weightliftingwarehouse’s amazon store. I think the COT-2.50 were $10 more and double the width but I don’t know whether they’d hold any tighter.

        • jburgeson September 28, 2015, 11:14 pm

          I don’t know too many people with collars for hanging chains to be honest… I don’t think you’re missing much until you get pretty extreme with the power lifts. The difference in those Ivanko collars is just a matter or weight. Functionally I believe they would be the same.

          OSO collars are pretty new so there isn’t any indication on how long they last yet. It’s probably a while though. Since they’re basically just vanity collars, I haven’t bothered to drop the cash for them yet myself. Someday I may test them though.

  • Devin September 28, 2015, 11:21 pm

    Looks like the good people over at again faster made some klokov collars…. let’s hope they hold up better than their bars! I just got in a pair… school is kicking my ass and getting over strep though, so haven’t touched a barbell in 2 weeks. Will try to remember to give you an update once I’ve put some time on them. But, overall I like the design, though I would have preferred a single screw instead of dual screw design (maybe that’s to help balance?).

    • jburgeson September 29, 2015, 9:13 am

      You gotta turn both screws on each collar to tighten? Is it just a bolt that runs straight through into the bar or is there an actual locking mechanism?

      • Devin September 29, 2015, 9:24 am

        Yea… it’s just like every competition collar, just with two screws. The screws tighten down on an internal sleeve that tightens onto the bar, holding it tight. This brand elected to use two screws, each 180* from each other, instead of just one. I put it on my bar to make sure it fits, and tried tightening just one and, while it held, didn’t seem nearly as secure as tightening both.
        In case you are unfamiliar with oly collars, once you tighten it to the bar itself, there is then a screw mechanism that pushes on the plates to keep them tight on the bar.

        • jburgeson September 29, 2015, 9:42 am

          Right, yeah I got that. I was just making sure that they weren’t just the screw into the bar like some of the more affordable weighted collars. Calling something “competition” these days doesn’t mean squat really. They call the Klokov bar “competition.” It’s like a catch-all term now rather than something that indicates that the equipment is actually certified and stage worthy/legal.

          • Devin September 29, 2015, 10:56 am

            So typically comp spec means literally that. E.g. 28mm bar vs 28.5mm, etc. not necessarily comp quality. Granted, this is dependent on the brand, if they offer truly certified competition equipment or not.
            As far as Jeremy’s comment. The collars are staying tight on the bar, the important part. Most collars I’ve seen loosen up after a drop or two as far as the screw mechanism against the plates. Every oly comp I’ve watched, the collars HAVE to be retightened after each lift. Part of it is all the metal to metal contact. Placing a rubber spacer between the contact points, a la DHS, helps this, but those loosen up too (I had those for a while). As long as it doesn’t slip on the bar sleeve itself, I’d be happy with them.

  • Jeremy September 29, 2015, 10:38 am

    I considered getting Again Faster’s Klokov collars, too. They look nice.
    Might get them later on.
    Comment #257 on this forum said that they kept coming loose though:
    http://forum.bodybuilding.com/showthread.php?t=113290471&pagenumber=9

    There were also some comments regarding the design of the OSO collars.

    • jburgeson September 29, 2015, 10:48 am

      I took a look at that. Interesting. Would be curious to see if more people end up having that problem with them staying tight. “Comp” collars coming loose is kind of a deal breaker, but QC isn’t amazing over there and it could be an isolated issue.

      • Devin October 2, 2015, 8:32 pm

        Well… after one use, I’m contacting the company to return the collars. The small, shitty, eyebolt screws do not allow enough of a lever to tighten the collars to the bar. I would have been fine if it was just the pressure part pushing against the plates that loosened up, but, after a drop from about shoulder height, the collars slid about halfway across the sleeve. More weight added caused them to slide less, I presume due to less bounce. But, doing just 45 kg…. or anything when it was just the green plate, caused quite a bit of sliding. Yellow plates were better but still sliding, same with blue and red.

        • jburgeson October 2, 2015, 9:24 pm

          That’s unfortunate. I guess I don’t need to add those to this page then.

          • Devin October 2, 2015, 9:29 pm

            Yea, I’d say not. Too bad. Not just gotta decide what I want to do. I liked the DHS collars, but after my debacle with them, I don’t want them to get any more of my money. ZKC is an affordable option, maybe just bite the bullet and get the Eleiko comp or Werksan training collars. Tough decisions.

          • Devin October 13, 2015, 12:44 am

            So, for an update… I contacted Again Faster. They requested video footage. Initially I was annoyed, but accepted, however it was good they did. The second time I used them, worked just fine. Slipped a little more than I would like, but acceptable for competition collars. The third day they were a little better as well. Must have been some type of shipping/manufacturing grease on the inserts inside the collars that caused them to slide so much that first day.
            While I’m not 100% sold on their design, I think they are a great option for $100. I will probably replace the eye bolts with something similar to the DHS collar’s bolt.
            As far as accuracy. I weighed each collar. One came in at 2.509 kg and the other at 2.511 kg. That’s basically a matter of shaving off a little of the rubber coating on the eyebolts to get them perfect. Not too shabby for $100.

              That’s good to hear. I suppose that’s not too unlikely to have the thing covered in grease or oil. For non-certified collars, weight deviations of +9 and +11 grams seems pretty solid so that’s good too.

    Hey, I’m looking at OSO collars and I noticed that the Rogue ones are listed as .8 lbs PER PAIR and the Vulcan ones are listed as 1 lb EACH. FringeSport doesn’t list a weight. They are all made out of the same 6061 billet aircraft aluminum, and I had a suspicion that they are all made at the same place (due to the similar look and pricing of pretty much every OSO collar I’ve seen online). Can anyone verify the weight of the Vulcans or speak to why they might be so different than other OSO collars?

      I don’t have the answer, but I can’t imagine how those could weigh anywhere near a pound each. Not aluminum.

    Well, I talked to Vulcan and they say it’s a typo. She weighed a pair and it came out to .835lbs for the pair, which makes a lot more sense. If they were 1 lb each I was going to consider them as fractionals in addition to collars.

      That’s good to know that they are consistent after all. Thanks for updating.

    My partners and I started a small business to make weightlifting quick and easy. We created SnapClips, a SnapClip is an innovative way to secure free weights. We are doing great in our Kickstarter campaign, and we would be ecstatic if you guys can check it out.

    Hi JB,
    Have you seen or heard of set wear boa clamps?

    • jburgeson October 6, 2016, 11:37 pm

      I’ve only seen pictures of them. I haven’t heard anything one way or the other. For that kind of money I’d probably spend a bit more for weighted collars, but to each his/her own.

    Hey I´m a gym owner. Functional/unaffiliated crossfit (call it what you want, we actually just do trainnig) :)

    The OSO collars a really good and keep tight on the bar. BUT the collars cut in to rubber bumbers and makes a circle rift around the metalring, and the rubber around the metalring eventually losen to a point where it gets unstabil just standard.
    We have Eleiko plastict technique plates.
