WHEELTOP EDS GeX Review: Hacking a 13-Speed SRAM Cassette with Wireless Shifting!

What's up, guys! Today we’re diving into the WHEELTOP EDS GeX gravel groupset. Right out of the gate, the packaging is incredibly clean and professional. The shifters come with carbon levers and have a very premium feel. One thing to note is that while the hoods are labeled 'TX' (the road version), they are essentially the same ergonomic shape and pair perfectly with the GeX rear derailleur. The GeX derailleur itself is a rebadged version of the OX 2.0 mountain bike derailleur, featuring a strong clutch to prevent chain slap and a magnetic charging port—though that port cover is still a bit finicky.

What makes this system truly unique is its versatility. I’ve paired it here with a SRAM Explore 13-speed cassette and a flat-top chain. In the WHEELTOP app, you can manually set the system to anything from 7 to 14 speeds. The setup does require some technical patience; you have to perform an initial calibration on the smallest cog and then fine-tune each gear's position using numerical values in the app. I also reconfigured the buttons so the left shifter handles easier gears and the right shifter handles harder gears, similar to a SRAM eTap logic.

On the road, it performed flawlessly. Even under a 400-watt load, the shifts were crisp and immediate, especially in 'Racing Mode.' The new hydraulic calipers are lighter and more refined than the previous generation, and since they use mineral oil, they are compatible with Shimano or Magura parts. If you’re a rider who loves to 'tinker' and wants a groupset that can adapt to different wheelsets and cassette spacings, the EDS GeX is an absolute winner. Just be patient with the initial app tuning, and you’ll have a professional-grade wireless system at a fraction of the cost.
