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.
