Sram Rear Caps Hub has 11-speed XD driver body. Axle made of tapered aluminum. Tapered aluminum axle is stronger without added weight. Fits all axles types. Ratcheting up the smarts. Finish: black, red and sand blasted; black, silver and polished. This straight-aligned, 4-pawl design turns the 26-tooth ratchet ring into 52 points of contact. The result: smooth 6.9-degree engagement without reducing tooth size or offsetting internal geometry-which means serious long-term durability. The only adjustment theyll ever need was made back at the factory. Every part of the ball bearing comes from the exact same supplier-which means that each bearing bore can be precision machined to fit the bearing race exactly. With tolerances this tight, the days of adjusting play after every ride are over.
