OSO Barbell Collars

OSO Barbell Collars are made in the USA from the same type of 6061 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 great color options.

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

Rated 4 out of 5 by from OSO Manufacture Deformity Great product from Rogue overall. Collars don't get loose while dropping heavy sets. With first use OSO collars are snug then become easy to slide. Great product to avoid scratching your barbell. Now for what your paying for I'm surprised how it arrived one collar has a manufacture deformity as seen on picture yet serves its purpose. Not what I expected from Rogue for the price tag on the OSO collars. Overall love these collars and Rogue you might need to reevaluate your product before its sent out to avoid manufacture deformity to leave the warehouse if so there is a Boneyard section to serve its purpose. If it weren't for the deformity I'd rate it a 5 Star product.
