    • The BBInfinite BSA DUB Ultra-lite ROAD Threaded External Cup Bottom Bracket System works with any DUB (29mm) road crank set on the market.
    • Weighing in at a skimpy 68 grams for the set, the Ultra-lite BSA DUB bottom bracket for road bikes delivers smooth, quiet, durable performance in an ultra-compact form factor that allows maximum clearance for power meter back plates. No big, special wrenches needed, just the good old Shimano classic TL-FC33 or ParkTool BBT-19 everyone already has.
    • 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 if using a road crank or 73mm if using a mountain crank set.
