Italian Threaded Shimano Road Bottom Bracket

Info Installation Instructions Installation Video Specifications These BBInfinite Threaded Bottom Bracket Cups work with all Shimano HollowTech road cranksets on the market, from Tiagra to Dura Ace. This Shimano Italian threaded bottom bracket features alloy cups that are MilSpec MIL-A-8625 Type II anodized for extreme durability. Polymer labyrinth seal bearing covers with integrated bushings keep out dirt and debris while isolating the steel bearing races from the steel spindle, halting creaks, corrosion, and accelerated wear of the crank spindle itself. The external cup bottom bracket installs with common socket-style, 16-notch tools such as the classic Shimano TL-FC33, Park Tools BBT-69.2, and many others. Take a look at this threaded GXP bottom bracket cup for road bikes for an option that is compatible with Sram, Cobb, and Quarg cranksets.
