Ultra-lite Road English Threaded (BSA) External Cup Bottom Bracket for 30mm spindle crank sets


Size Guide
Thread Style

  • 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.

    NOTE: FSA 386Evo cranks WILL NOT work with the Italian threaded version of this product due to the the standard's  70mm width. This applies to FSA branded 386Evo cranks and Italian threaded bottom brackets only.

    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 to 68mm for English or 70mm for Italian.

    Both English and Italian version are 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.
