Overview
OSO Mighty Axle Collars 2.0 are specialized, lightweight barbell collars engineered specifically for specialty bars with a 1.9" outside diameter. Manufactured in Columbus, Ohio, these collars utilize aircraft-grade 6061 billet aluminum and a high-friction rubberized lining to provide a "lockdown" grip on smooth pipe sleeves where standard Olympic collars often fail. The 2.0 version features a notched flange design and a distinct red anodized finish for quick identification in a busy gym.

Performance Benefits
Axle-Specific Security: Standard collars often slide on 1.9" pipe because they cannot compress enough to create friction. The Mighty Axle Collar is precision-sized to "bite" into the pipe, preventing plate drift during high-rep axle cleans or deadlifts.
Lightweight Precision: At approximately 0.16 LB per collar, they add minimal weight to the bar, ensuring that lift totals remain accurate for competitive training.
Rapid ID: The bright red anodized finish and unique notched edges allow gym owners and athletes to immediately distinguish these from standard Olympic collars (usually black or silver).
One-Handed Operation: The cam-lever is designed for ergonomic, fast transitions, which is critical for timed workouts or multi-athlete sessions.
Maintenance and Care
Lining Cleaning: Periodically wipe the interior rubber pads with a damp cloth to remove chalk and dust. A clean surface is essential for maintaining a "vise-like" hold on smooth pipe.
Anodization Care: To preserve the red finish, avoid dropping the collars directly onto abrasive surfaces like concrete or steel diamond plate.
Lever Check: Verify the lever "clicks" firmly into the locked position. If it feels loose, check the interior pads for excessive wear.
Warranty Information

Frequently Asked Questions
Q: Will these fit my standard Rogue Ohio Bar? A: No. These will not fit any bar with standard 2" (50mm) sleeves. Attempting to force them on may damage the collar mechanism.
Q: Why are they notched? A: The notched flanges are a visual and tactile indicator that these are axle-specific collars, helping prevent athletes from confusing them with standard OSO Mighty Collars.
Q: Are they sold as a pair? A: Yes. All OSO Mighty Axle Collars are sold and shipped as a pair.
