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.

Yeah, I was close to buying the Sram outfit, but went with wheeltop. https://thebrig.com.au/products/sram-mullet-upgrade-kit-x01-force-etap-shifters?Title=Default+Title.

Only time will tell if it was the correct decision, at the moment I'm still working through the initial gear indexing which has been slow and frustrating.... note that the frustration may be from my lack of skills and learning as I go, I've only ever fit and tuned mechanical before.

Help please - I'm trying to setup my GeX groupset, so EDS  but 1x I guess.

Problem: I'm trying to initialise the rear mech, but it will not go down to sprocket 1 (smallest).  On my 12 speed it will only go as low as cog 3, on my 11 speed it won't go past cog 2.

In the app I'm in initialise, trying to move it down/right, but it won't go any further, after a certain point a beep sound indicates there is no more down/rightward adjustment.

Any ideas?  I haven't touched the limiter screws because it seems too odd for the limiter screws to be soooo far off when it's just out of the box, new.  However, I have also noted that the top limiter screw isn't set because I can shift right off the top of the cassette.

Note that it does shift from gear 3 upwards, that's all working well, it knows that cog 3 is gear 3, but still won't go down to cog 2 or 1.

Without adjusting limiter screws, and this would be a big adjustment, I'm stuck and looking for help/ideas please.

I was in the same position but on Taobao.  I went with the aluminium levers which were part of the package.  When I looked into it the difference was something tiny like 20g total..... although 'carbon levers' does sound good.  I got mine for exactly the same price, lets hope it works out OK.

 
roughly $700 for this group with sketchy warranty vs another..........

Interestingly here in OZ you can get a SRAM mullet upgrade kit (Force shifters, Eagle derailleur and Force brakes) for the same price as the Wheeltop.  Yes the Sram requires XD hub and Cassette to get the 10-52t.  However, it enables a bigger spread of gearing, bought locally with Sram quality and support.

Makes for a tough choice.

Someone mentioned the wheeltop ability to tune individual gears/sprockets.  I see the benefit of this, but I can imagine that once you start you never stop tinkering until it drives you made, whereas the Sram should 'just work' out of the box.

I'm interested in the Wheeltop, very interested, but I would have expected 33% cheaper than Sram electronic.  I have an Xcadey power meter and top end Chinese wheels, both are great, the companies are great, but when things go wrong it still takes 2-4 weeks to xchange info and actually get any new parts from the time I raise an issue..... not necessarily the fault of the company but the geographical and communication logistics. I'm not complaining here because the products were somewhat cheaper than local mainstream alternatives...... and this is without talking about going into a local bike shop for help, and the look they will give you when they realise you have an unknown groupset for which nobody has been trained or carries parts.

All food for thought, I was super excited for the Wheeltop groupset, but the price has put a damper on that excitement.

I certainly wouldn't be making a decision based on reviews on their website.  The video review was interesting but just a first ride, and many social media influencers will give anything a good review as opposed to an honest review.  I think Wheeltop has given a number of groupsets free to online reviewers, eg. Ribble Valley Cyclist's 2nd GeX Vid . Not saying the reviews are honest.

Time will tell, more real reviews, durability feedback, etc.  Also, when things do go wrong, how good is the support.  Everything might be wonderful until it's not

Interesting that this is max 51t cassette, whereas the mtb version is 52t.

Looking forward to reviews and pricing.  I've seen Sram mullet mini groupsets for $750... however this Wheeltop would allow the keeping and using of 11sp cassettes, chains and freehub bodies, which is additional cost saving initially, but with options to uprade to more gears later.

Update, Wheeltop website is around $675, so not a big difference from Sram..... Sram comes with the comfort of local support (I'm in the process of replacing an chinese power meter crank on warranty, local support would've been easier and quicker, even though the manufacturer was very helpful)

Found this on Taobao, looks very similar to the GeX in the video https://item.taobao.com/item.htm?abbucket=16&id=821778355114
