OSO Axle Collars - Red

Designed exclusively for use with 1.9" OD specialty bars, OSO's Axle Series collars feature the same aircraft-grade aluminum construction and rubberized interior lining as the standard OSO barbell collars. Normally available only in olive green, this Rogue-exclusive version of the OSO Axle Collar comes in red.

The Axle Series is manufactured in Colorado and compatible with a broad spectrum of specialty bars, including the Rogue Axle, TB-2 Trap Bar, and Log Bar. The locking clamp ensures a secure, stable hold through repeated, high-impact drops, and allows easy adjustments or removal with a simple lever and lock/unlock mechanism.

IMPORTANT: Because of their smaller diameter, OSO Axle Collars CANNOT be used with standard 1.98" (50.4MM) barbells.

OSO Red Axle Collars is rated 4.4 out of 5 by 12.
Rated 5 out of 5 by from These are awesome Absolutely must have for the big trap bar and I assume other Rogue bars. These grip the bar like crazy and I have not made them slip yet. They open enough to go on the bar easily not like some you have to fight with to get on the bar.

Rated 5 out of 5 by from Axle Collars Lock Tight I have been using these collars for a couple months now. I'm 100% satisfied. They lock plates on as tight as you could possibly want with no slipping during a large set of reps or even during a long WOD.

Rated 3 out of 5 by from Meh. Go with the Rogue collars instead. I’ve had the Rogue collars for almost 1.5 years, but decided to get these to go with my new Rogue SSB, and while I like the splash of color I overall regret the purchase. Firstly, they don’t function as smoothly as my Rogue collars - opening and closing them always feels a chore, and happens in steps (80% open, 95% and then 105%). Just as badly, they arrived with poor paint (see photo near the clasps). I probably should have returned them, but it seemed a hassle in a time of stay-at-home... still, while they function well enough, there are better places to spend your money. And I normally love Rogue kit.

Rated 5 out of 5 by from Works Great Works great on specialty bars which have smaller diameter. I’m using them on the LT-1 50 CAL TROLLEY and the TB-2 TRAP BAR

Rated 4 out of 5 by from Great equipment! Built well, as with all Rogue products. Lacking in Rogue branding on the item though. Maybe the Product Design team could look into this.

Rated 5 out of 5 by from Works as advestised I bought these along with a trap bar. At first I couldn’t make them fit the bar. The collars seemed too small. I realized after looking at the lock cam mechanism the collars will open wider than I first tried. Once I pushed the lever fully open it slipped onto the tap bar with out a problem. The collars work great.

Rated 1 out of 5 by from Does not fit on trap bar These collars were depicted on the same page and next to the trap bar, as in “these are the collars you need.” Well, they don’t fit (too small). They look great and probably work well for a small bar, just not a trap bar.
