Collection: Cassettes & Cogs

Cassettes and cogs define your gearing range—shaping cadence, climbing ability, and top-end speed.

Colorado Cyclist stocks options for road, gravel, and MTB drivetrains from brands like Shimano, SRAM, and Campagnolo, with choices spanning close-ratio road gearing to wide-range off-road cassettes. Proper cassette selection improves shifting performance and helps match gearing to terrain and fitness goals.

Replacing worn cassettes keeps shifts crisp and protects your chain and chainrings.
