OSO Barbell Collars

OSO Barbell Collars are manufactured in Columbus, Ohio from the same type of 6061 Billet Aircraft Grade Aluminum alloy used in aircraft construction. The OSO Barbell Collars deliver on functionality, too--creating a secure hold on the bar through repeated, high-impact drops, and allowing easy adjustments or removal with a simple lever and lock/unlock mechanism.

All that being said, the first thing a lot of lifters talk about with the OSO Barbell Collars is how they look. Shaped like an industrial gear, the collars' old-school design is paired with some bright color options: blue, green, orange, pink, purple, red, gold, and gunmetal.

For Oly lifters, CrossFitters, or any athlete looking for an upgrade from basic spring collars, OSO Barbell Collars are a nice option.

Already broken
I loved these collars. When clamped, they don’t move and keep my weights on the bar tight. However within 2 months the black clamp piece of one of the collars has already broken off and I can no longer use it. For the price, they did not last long.

Can’t believe the metal split in two!
I bought these a while ago… more than a few years (definitely more than the 2 year warranty period)… but for a guy that works out about 2 times a week and doesn’t use collars for every workout (actually didn’t use them even once during CoVid gym closures), I would have expected them to last a lifetime…. Nope! See the pics. Aluminum as a material doesn’t like bending and flexing which is what happens when you close the collar. Looks to me like the “aircraft grade aluminum” fatigued and cracked. Meanwhile the plastic lever, steel roll pins, and rubber lining all look fine. Imagine my shock while doing cleans as the collar got more difficult to slide on and the eventually wouldn’t close and caused me to stop and take a closer look, See pics.

Colors aren't even close, plastic wears out
Just got my second set of Oso because the first ones stopped clamping. The plastic wore out. Super bummed that the purple shown online isn't even CLOSE to the purple I received. Definitely would have gotten a different color if I knew how off it would be. Too expensive to be such a bummer product.

Plastic lever broke
I received this as a gift for Christmas and only used a handful of times before the plastic lever broke.

The plastic clip broke with littleTo no effort.
Although i bought thr clamps about 2 months ago for my stepson, who im teaching the basics of Barbell Lifting, after about 10-15 uses with moderately light practice weights, the plastic clamp on one clamp ahattered when pushing down.

Cheap plastic levers
Waited over two weeks to get these collars just for the plastic lever to snap the second time I used them. Whoever thought it would be a good idea to use the cheapest plastic on these collars obviously never actually tried them out.

Perfect for Olympic Dumbbells!
I went through 4 different sets of collars on the market before I got my hands on these. My Loadable Olympic Dumbbells are no longer a safety hazard for overhead work, skullcrushers etc. Once you lock these guys on, the plates are going nowhere, they are locked on for good!
Yes, I recommend this product

Works perfect
I often use these collars with the loadable Dumbbells (DB-15), so they need to be really secure, which they perfectly are. I live in Europe and I ordered them in the US, the shipping was fast and cheap and Rogue's service was great.
Yes, I recommend this product
