So, there has been a fair amount of chatter in the last year+ about the new electronic shifting gravel groupsets from China. LTWOO got to market first with the eGR and you can read my writeup of installing that here . But more recently Wheeltop came out with their equivalent GeX system ( Installation writeup here ). Initial pricing on both was almost too good to pass up as an experiment and I did so. Current pricing is still quite competitive vs even the lowest end electronic shifting from SRAM or Shimano but not the 'no brainer' it was at first. Highlights of these systems: Both 'groupsets' are really just 1x mini groups. They both include: Rear Derailleur Brifters Brake calipers Charge cable (use your own USB brick) For a full groupset, you will still need to provide: Crankset/chainrings (1x only with GeX and eGR. Both have road 2x options) Chain Cassette options: Wheeltop GeX 3-14 cogs, 10-52 teeth LTWOO eGR 10-12 cogs, 11-46 teeth officially. However, I've run ...
I've already had experience with the first of the new, value-priced electronic groupsets from China in LTWOO eGR. You can read about that experience here , but in summary it's pretty good but wasn't perfect for my application for two main reasons It expects to stash the battery inside the frame and have a wire run out to the derailleur. Unfortunately, my V1 Cutthroat isn't set up that way and I had to strap it to a bottle cage in a less-than-pretty way Officially it only supports up to a 46t cassette and I run a 50t. It does actually work, but it's a little cranky about it in setup and operations. But along comes the Wheeltop GeX solution. Same idea from a company that has been making components for others for many years and MTB electronics for a couple of them. It promised to address my issues in that it uses a battery attached to the rear derailleur directly and officially supports 51t cassettes. Reports are the...
