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
