It has serials - I don't think it's a problem of identifying their own product but rather they've come the decision that the purchasing retailer/channel is who would handle warranty issues.  For my issue with the adjustment screw, the AliExpress seller was happy to deal with it, I just had to get it back to them in China.  I ended up just fixing myself.

Definately will limit acceptance outside of Asia until they can improve servicing globally. Unfortunate.    It will be a small niche of people like the ones in here willing to accept the servicing hassles that will be buying.

Yeah, especially with electronic... When you buy a Chinese mechanical group, a lot of the times you can replace the parts with Shimano or Sram when something is not right... If your Chinese electronic group fails you could be out of a bike for 6 weeks...

This is pretty dumb. How hard is it to assign a serial # to each groupset? Their warranty process is just pure laziness. The EDS TX is already in Shimano 105 Di2 AliEx pricing territory. At least with the 105 Di2, spare parts are plentiful and quality assurance to chance buying from a reseller is much better.

Vulcanizing Cement is what I always used to repair cuts and apply plug patches in motorcycle and automotive tires.    Clean the area really well with the companies prep chemical or rubbing alcohol works well to.  A little scuffing with some sandpaper before cleaning is good practice as well.

This is enough for 100 tires; https://a.co/d/cGj5RdF

They work fine! I double checked my gravel bike brake pads which does long descents on dirt trails and there are no deep track lines on the pads. My 2x160mm rotors are 1.6mm thick and feel quite sturdy. For someone to toast their rotors and dig tracks into their brake pads suggest to me they weighed like 130kg and had zero clue how to feather and modulate front/rear braking! There's a reason they have bigger rotors for bigger riders!

A bad design is a bad design though. Glad it's working for you, but as a fat ass myself, i dont want half of my rotor surface to be air.
