BSA English Threaded for 30mm Road spindles Ultra-lite Bottom Bracket


Size Guide

  • The BBInfinite Ultra-Lite Road Threaded BB System works with any long-pattern 30mm spindle road crank set on the market such as a Sram Red BB30/PF30 crank, Lightening, THM Clavicula, Rotor 3D+, FSA 386 Evo, and Easton EC90, just to name a few.

    Not compatible with the Rotor Aldhu Track crank set. The crank is too narrow and will not fit.

    Weighing in at a skimpy 71 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 the common BSA threaded bottom bracket socket-style, 16-notch tools such as the classic Shimano TL-FC33, Park Tools BBT-69.2, and many others. When installing this threaded BB for 30mm spindle, 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. Check out our bicycle parts and kits to find the correct installation tool for your threaded bottom brackets.

    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 to 68mm for English.

    Not compatible with any "BB30 Only" crank sets such as the Cannondale Si series, any Specialized FACT or S-Works crank, or any other short-pattern spindle 30mm crank set.
