Gear Components

Some bike parts have a longer lifespan than others. Chains, cassettes, and bottom brackets and various other gear components fall under 'routine maintenance' items as they wear out and become less efficient with regular use.

At Sigma Sports we offer a wide range of gear and drivetrain components for all bike types, including road, gravel and mountain bikes with gear components from leading brands like C-Bear, Shimano, SRAM, Campagnolo, CeramicSpeed, Kogel, Wheels Manufacturing and KMC.
