Bike Parts & Drivetrains

Drivetrain components, wheels, brakes, and suspension parts for upgrades, replacements, and builds. This collection covers the parts that actually change how a bike rides — cassettes, derailleurs, chains, and cranksets for drivetrain upgrades; rotors and pads for braking performance; and suspension components for fine-tuning ride feel.

Compatibility is the main thing to check before buying: drivetrain parts are generally grouped by speed count (11-speed, 12-speed) and brand ecosystem (Shimano, SRAM), and mixing across ecosystems doesn't always work cleanly. Wheel and suspension parts depend on your frame's specific standards (axle spacing, travel, mount type).

Each listing calls out compatibility requirements directly, so you can check fit before you buy rather than after.
