    • The BBInfinite Ultra-Lite MTB Threaded BB System works with any long-pattern 30mm spindle mountain bike crank set on the market such as any Sram MTB crank, Rotor REX, and all the RaceFace Cinch cranks, just to name a few.

      NOTE: WILL NOT work with any BB30-only cranks with short spindles, such as the Cannondale Si Hollowgram.

    • Weighing in at a skimpy 64 grams for the set, the BBInfinite Ultra-lite bottom bracket system delivers smooth, quiet, durable performance in an ultra compact form factor that allows maximum clearance for power meter back plates. No big, special wrenches needed, just the good old Shimano classic TL-FC33 or ParkTool BBT-19 everyone already has. Do not use open end wrench-style tools because they will slip and mar the finish, and let's face it, that ain't pro.

    • ATTENTION: Always "chase and face" your frame bottom bracket shell before installation. Threads must be absolutely clean and clear of debris. Frame bottom bracket shell must be faced.
