Wheeltop Groupsets

Wheeltop manufactures wireless electronic groupsets that bring cable-free shifting to road and gravel bikes at an accessible price point. The TX series delivers road-specific wireless shifting compatible with Shimano drivetrains, while the GeX series covers gravel and mixed-terrain setups with wider gear ranges.

Wheeltop groupsets feature rechargeable batteries, wireless communication between shifters and derailleurs, and a straightforward installation process. Pair with a complete bike or frameset build from Underdogs Cycling.

Sourced factory-direct, Wheeltop's TX road and GeX gravel systems make wireless electronic shifting genuinely affordable, backed by warranty and tracked worldwide shipping, and install with familiar tools. Switching from a mechanical or another electronic groupset, or unsure which system suits your frame, cassette range and brake mounts? Send us your current setup and we'll confirm compatibility and the right variant before you order. Pair a Wheeltop group with a fresh crankset and chainrings for a complete drivetrain upgrade.
