Our BBInfinite SRAM DUB English/BSA/Euro Threaded External Cup Road Bottom Bracket System works with any DUB Road (29mm) crank set on the market. This includes DUB SL and DUB WIDE variants. Weighing in at a skimpy 68 grams for the set, the Ultra-lite DUB bottom bracket 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 such as our own here.
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 68mm for BSA road applications. If it is at 68mm, do not face it more. In this case simply chase the threads, clean, and install according to instructions.
