  • Our BBInfinite DUB Ultra-lite Threaded External Cup Italian DUB 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 Italian 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. The English and Italian threaded bottom brackets install with common socket-style, 16-notch tools such as the classic Shimano TL-FC33, Park Tools BBT-69.2, and many others.

    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 70mm for Italian.

    ABOUT OUR BEARING CHOICES:

    Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime warranty.

    ABEC-7 Steel Bearings: Crafted from SAE 52100 chrome steel, our BBInfinite ABEC-7 (ISO 492, Class 4) bearings are so buttery that you’d have to buy our Ceramitechs to find anything better. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber or Koyo. 1-Year Bearing Exchange Warranty.
