Who it suits

The grip is the reason to buy this bar for squat, bench and deadlift. Pay for the stainless/chrome configuration when you want that exact shaft and sleeve finish.

The drawback

The pronounced knurl is a deliberate powerlifting choice. REP’s milder Colorado is the alternative for frequent cleans or more varied barbell sessions.
