Spin-Lock Collar Replacement
The same spin-lock collar that shipped on your EZ-Series bar — factory-matched material and bore size, sold single or in a pair.
Match material first, then bore size
One wrong ring and the sleeve spins loose under load — these are the only two things that matter before you order.
Not sure which bore you need? Measure the sleeve pin your old collar sat on — 1"/28mm is a standard bar, 2"/50mm is an Olympic sleeve.
Why the spin-lock matters
The collar is the only thing keeping the sleeve locked to the bar under load. A worn thread or a cracked nylon ring lets it walk loose mid-set — that's a dropped weight, not a cosmetic issue. A factory-matched replacement restores the original clamp force; a universal ring usually doesn't.
- Same bore tolerance as the collar your gear shipped with
- Thumb-screw torques down without stripping the thread
- Order a pair if both sides are worn — most riders replace in twos
