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

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.

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

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 common socket-style, 16-notch tools such as the classic Shimano TL-FC33, Park Tools BBT-69.2, and many others like our own right here. 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.

Q: Why is there an Integrated Spindle Protector option? A: Some frames have extremely restrictive bottom bracket shells that get so narrow in the middle that there is barely clearance for a 29mm or 30mm spindle. A frame of this type will NOT admit our integrated spindle protector. If the frame is wide open inside, chose the "With" option. If your frame narrows inside, chose the "Without" option.

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 the proper spec for that frame, for instance, a 68mm shell should measure exactly 68mm after facing. If it is at spec, do not face it more. In this case simply chase the threads, clean, and install according to instructions.
