There are aftermarket cassete options for 12sp that will work on your 11sp HG freehub.  You dont have to buy new wheels for that.

Yes, I realised that, I've gone with a Spedao lightweight 11-50t cassette which is 25% the price of an equivalent weight sram cassette.  I'm still thinking of going XD on my road bike wheel in order to go down to a 10t cassette.

10t cog is not that efficient. Quadratish, not praktish, not good. :)

What you lose in efficiency you gain in flexibility, especially if you are 1x and limited by chainring size.

But you're not wrong. I have a 10t and it always horrifies me when I turn it on the stand and FEEL what seems like grinding in the drivetrain. Eeeek yuk.  But, on the road/trail, it's really not noticeable and having 10% more range is nice when you need it. But honestly, I have few rides where I spend a lot of time in the 10t

It's ok for MTB: when you need that exrta speed on a descent for a small amount of time. But for the road, i think its not worth it...

FWIW - I got stung with significant customs charges for my groupset from TWITTER Bicycle Factory. I order a lot from Aliexpress and nearly all of it gets through no problem with no charges. Can just be a luck of the draw and choice of carrier, I'm sure.

Does anyone have a video guide on how to micro adjust? I cannot seem to make it shift smoothly.

What country are you in?  Could it be that it's over a daily threshold for duty-free. Apparently in the US, for example, under a few hundred $ in a shipment it gets the same exemption as hand-carried goods on a flight. But over that, duty schedules kick in. I had an Italian vendor know that and send me two packages instead of one for a groupset which was interesting. (I looked it up later)

Are you using the app in fine tuning mode, you can set the offset number for every gear, the settings are very fine for micro adjustments, so far I have always changed in jumps of 5

My GEX has arrived. Build quality seems quite a lot lower than Ltwoo. Hood rubber sticks out, RD finish is a lot rougher. Jockeys are *bad* (ordered hope replacements). That said, I am hoping that they made smarter choices than LTWOO - more serviceable, better charging point, more configuation options, larger range, better hanger connection. I'll update once it's had some ride time to compare more fully.

First proper ride with the new GeX today, 3 hours gravel and road.  It performed flawlessly, all gear changes were quick and seamless, braking was great, basically nothing to say but good things.  I swapped bikes with another rider who has Sram Force, he thought the GeX was just as good, pretty much the same.

My most pleasing feature was the shape of the shifters, much more comfortable than any of my previous Sram or Shimano, perhaps because I have smallish hands, I'm not sure, but I found them really comfortable.

I've done my build slowly, my first time fitting disc brakes and an electronic groupset, so I had a few learnings.  Some key points and info about my build:

  • I had to back off the K, lower limit screw in order to initialse my gear 1
  • I set up the gears, nicely indexed on the workstand, but during a short test ride I had to fine tune 2 or 3 gears, but this was really easy
  • The weight of the groupset was a tad lighter than my Sram Rival groupset
  • I'm running a Sram Eagle chain with a Spedao 11-50t 12 speed cassette, working well and very very light for the money
  • I did not need to bleed the brakes at all, had to shorten the hoses, insert new barbs, connect and go..... all good out of the box
  • The groupset comes with a bleed kit, nice touch
  • For shortening the brake hoses I bought a tool from Aliexpress, makes it so easy to cut and insert the barb, great investment
  • Total cost with brake hose tool, groupset and cassette ~$530 USD (I already had a chain

Next step is to see how easy it is to swap between wheels, one 12spd, one 11spd

Nice finishing touch to my Gravel bike:

  • Waltly Chinese Titanium frame
  • Wheeltop GeX groupset
  • Lun Grapid 650b wheelset
  • Spedao lightweight cassette
  • Uno Aliexpress lightweight bars and stem
  • 160mm Xcadey power crank
  • Oval chainring, Stone from Aliexpress
  • Kactus lightweight rotors
  • 2nd set of road wheels from Speeder Cycling
  • Branded stuff includes Sram chain, Pirelli Tyres, SMP saddle and XTR pedals (half price sale)

Also had my first ride today. Winter ride -5C, for 2 hours. Works flawlessly and the hoods are very comfortable for my small hands. I liked it. No complains. Fine tuning between gears was not needed. I've just switched it to 12sp (new ZTTO SLR3 11-46 12sp cassete) and setup initial gear with micro adjust.

Have to wait to see how it will last...

I still cannot make this thing to shift properly.
I overturn the H limiter and it fell off. Lol i cannot put it back.

Anyway living with it, turn off 1st gear and keeps on
Skipping 10th gear.. so its shifting 9th to 11th.

This! I borrowed an MTB last week w/a tiny chainring and never ran out of gears on the downhills w/a 10T cog. it's very counter-intuitive until you try it.

Initial Pairing Question:

So my GeX kit just arrived tonight and I'm wondering about pairing etc. The manual says to start with pairing but also that they come paired (hmmm).

Here's what I'm seeing:
- The shifters blink but do not actuate the RD
- The RD lights red when I plug it in (still waiting for it to complete)
- The app can find the RD to pair and name but nothing else.

Will this all sort out when the charge completes or do I need to start doing something?

Do the shifters have to be discovered by the app or does it come with the RD?
