The WHEELTOP EDS GeX Gravel Hydraulic Disc Brake Groupset is a wireless electronic 1x groupset that offers exceptional versatility (3–14 speed compatibility), strong hydraulic braking, and a very competitive price compared to SRAM and Shimano electronic groupsets. However, it is consistently criticized for a finicky app, awkward charging port, non-removable battery, and inconsistent long-term reliability and customer support. It represents a high-value but less polished option for DIY enthusiasts willing to tolerate setup quirks.

I just wanted to add my 2 cents to this convo. I am a dealer for wheeltop and have set up a few bikes with the road gruppo. I am no where biased to wheeltop as I am a shimano fanboy. What I can say about the gruppo is. 1 it was a pain in the ass first time around to set up the fd as someone else has said here the trim screws do nothing. The Rd is clunky. The app sucks. Now haveing said all that once I got over the first time pains and I went on to insatll it another time on another bike I can say. Fd was a breeze to set up the app still sucks but what it does allow is great. It allows you to use 3rd party cassettes and trim them perfect for flawless shifting. I wish the group was much lighter but app its in the works. Being from canada I had a issue with 1 of the shifters. Customer service from the wholesaler was fantastic. I will say this if the group was the same weight as a duracace and im fine if the gruppo was more money it would be my gruppo of choice.
real world exp. here... mounted on my gravel Niner RDO 46/30 ... 11-34/11sp (edubied monoblock) absolute no glitches whatsoever...it just works, now since May! Yes, setup isnt for the 'faint-hearted' but hey...its still fun...from what i saw, they updated some of the setup instructions/videos. App design still quite the same...which is a bit...weird... and whats really amazing..you can finetune each cog if needed...e.g. range of 11sp cass...gives you around 0-1800 index units in the App so for every step you have roughly 180 IU to play with...to give you an example how much micro fine tune is possible. it also has autotune for the FD... and FD is my only complain...being not as powerful under load for shifting.
