    • The BBInfinite DUB Ultra-lite Threaded External Cup Bottom Bracket System work with any DUB (29mm) road crank set (68mm or 70mm road bb format) and all DUB MTB (29mm) crank sets (73mm MTB format) on the market.
    • 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. 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 for English or 70mm for Italian if using a road crank or 73mm if using a mountain crank set.
