  • 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. Installs with common socket-style, 16-notch tools such as the classic Shimano TL-FC33, Park Tools BBT-69.2, and many others. 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.
