Finally received mine as well, and was able to go to a ride today. Setup experience is not the best, the shifter cover is ridiculously hard and the explanations in the manual/app not really helpful, but with the help of forum posts and youtube videos I was able to set it up perfectly, though I did have to play around with the fine tuning a bit. Braking performance and shifting is really good. The hoods feel comically small, not necessarily bad, but definitely something that I need to get used to.(and my hands are not exactly big) Overall I really like it, especially that I was able to get it from aliexpress around 410 euros.

The groupset is packed and shipped out now. The whole shipping, packaging etc. comes out to 47€. In addition to the 345€ i've paid so far i am at 392€ for the whole groupset. I could have optimized a little further by not shipping the whole packaging etc. but i didn't want the groupset to get damaged in transit.

I guess import taxes depend on luck and not included in this price, right? I bought mine on aliexpress, that after coupons(there is almost always a sale going on, now you can get it for 447 usd which is 409 eur)was 460$ which is 421 eur. A little bit more I guess, but thats fine(whether I will get taxes or not I don't know, the package is in europe but I have not received it yet). In my opinion 500 euros should be the price of the gex from the official store, otherwise as a new build it doesn't make sense to go with the gex for 600 euros when you can get an apex xplr groupset with a chain and cassette for 700 euros from bike-discount.de

Help with gearing?

I'm confused by Wheeltop saying minimum cog "10-11t". Does that mean 10t may have issues? Anyone with specific experience?

I'd like to get the additional occasional speed of 10t based on my browing of gear calculator. The 10t-45t shimano cassettes look good to me (even though I need microspline wheels), or there are 10-46t XD cassettes.

Better to be safe and stick with 11t?

I asked a similar question from wheeltop and they said that 10-44, 10-45 is absolutely fine, they had compatibility issues on some frames with 10-52 but not with 11-52. So I guess it is more of a capacity thing on the extreme ends, but you should be good with 10-45 according to them.

I don’t understand what’s the point with wheeltop gx, it comes for 600€ in EU, I just bought a sram rival axs 1x12 for 580€, same components. Yes the GX supports more gears and larger sprockets (…and I don’t care) but rival works very well out of the box, it’s reliable, waterproof and thoroughly tested. Should not wheeltop reduce prices?

Where did you buy it from for that price? I am looking for groupsets, and kinda set on the gex, and I can't seem to find a rival axs for that low anywhere, not even on ebay, etc.
