Mountain bikes, cassettes are traditionally 7-speed, 8-speed, or 9-speed, but are increasingly moving towards 10 cogs in newer systems from Shimano and SRAM. Meanwhile, 8-speed, 9-speed and 10-speed road bike cassettes are available from these manufacturers and also from Campagnolo. We also stock multi-speed freewheels, which tend to be found on budget bikes, and BMX freewheels.
