Our all new 11-speed road hubs for the Shimano, Campagnolo and SRAM XD cassette splines are available in two models. We have our Classic stainless steel version for those looking for uncompromising strength and reliability and a Pro version for those looking for a lighter weight option. For the Pro model of our road hub we replace the stainless steel cassette body, axle and end caps found in our Classic hub with anodized US-produced 7075 aluminum parts. This results in a 34% drop in weight (depending on hub configuration) when compared to our Classic hub. Our 11-speed cassette hubs come with a spacer so you can run a 8, 9 or 10 speed cassette.
