Info
ROLLCii external BSA bottom brackets are made in Taiwan from 6061-T6 aluminum and feature high-quality stainless steel or ceramic bearings, where available. We offer four different bearing sizes to help you fit your favorite crank to your favorite bike.
Note: Installing 29 & 30mm spindle BSA bottom bracket parts requires the ROLLCii 12/24T wrench, which is not included with the bottom bracket parts.
