We picked five collars for Olympic bars based on clamp strength, drop resistance and speed. See our barbell collars review for the full head-to-head, and our best 20kg men’s barbells and best 15kg women’s barbells if you need a bar.

Buying Guide: Collars for Olympic Bars
Check sleeve diameter
Olympic sleeves are 2 in. (50 mm). Worn sleeves can be slightly smaller, so a tight-clamping collar helps.
Drop resistance
For snatches and cleans, choose durable lever collars that will not pop off on impact.
Weight
Competition steel collars weigh 2.5 kg each; training collars are light and do not count toward the load.
Speed
Quick-release levers make plate changes fast in Olympic sessions.
