Acros Ceramic Bearing BB

The Acros ceramic bearing bottom bracket introduces several improvements over existing manufacturers' stock designs. The bearings are manufactured in an angular contact design, which improves wear life and reduces friction in real world riding situations. Internal bearing friction is further reduced by use of ceramic ball bearings and high-quality rubber seals. The aluminum cups are nicely finished with black anodiztion and laser-etched logos.

Compatible with all Shimano 7800 Dura-Ace, 6600 Ultegra, and 5600 105 cranksets. Cups threads are designed for English-threaded 68mm bottom bracket shells.
