First a disclaimer: I don't own one of these (yet?) but am doing some research and it seems to be evolving in interesting ways, at least for the US market.
1) You can now buy via a US store
https://wheeltop.us/products/wheeltop-eds-gex?variant=49584537895227. The price isn't quite as low as I saw on AliExpress a month ago but it is with warranty, a return option and free shipping. (Sorry to readers outside the US
2) Since the early videos and other reviews, they are now offering a double configuration of cage length and lever material. So you can get 51t compatible or not and/or CF levers or not. Cage doesn't change pricing but levers do at $40 (not bad if you
have to have CF levers
)
3) There appears to be growing confirmation that the battery pack CAN be changed out. Not field swapped but replaced if there is an issue. Still haven't seen the part, but the fact that the mount is there and the latest instructions refer to doing so is encouraging. (I don't care how good it is, batteries fail and/or wear out and not being able to replace in any way was a dealbreaker for me)
4) The most important thing to ME is that it supports an
11s configuration in addition to 12s (and more). This adds a lot of flexibility for retrofit. SRAM and Shimano electronic systems demand 12s setups. Since I'm putting it on a bike that has two wheelsets, each with 11s 50t cassettes, that's a huge extra cost (two expensive cassettes and one wheelset doesn't support a 12s freehub so...) to go even a Rival AXS setup. FWIW, I'm not finding a Rival shifter, GX MTB RD AXS setup for less than $800 just for those parts.
For some context,
I have 12s 2x Force D1 on a road bike and like it a lot. (And I stole the full groupset for $1k a year ago as a closeout) If I were building from scratch and didn't have to deal with 11s legacy, I'd be happy to build with that or the new Rival. I'm assuming the MTB RD works well given the experience they have. So no complaints other than price
I've also been running LTWOO eGR this season on the gravel bike. Same ability to support 11s and at the time was half the price of Wheeltop's current price so worth a punt. The good: Setup is fairly simple in general. BUT the calipers don't mount quite the same as Shimano and require an adapter plate that wouldn't fit on my frame. Some Shimano calipers fit instead though and work well with the LTWOO levers. Also, because LTWOO uses a Di2 power model (battery in the frame), and the frame I'm installing it on is not set up that way, I've had to frankenbike the setup. Battery status is a pain to monitor because the integration to the head unit is faulty (always at 'critical') and it is easy to fail to charge due to weak magnets and strange indicator lights. If you're interested, I've written more here
