Yet to try, but looks nice. The shifting gear is made of metal (aluminium I guess) to solve breakage issues of last version. Came without box but well packed. I guess that’s why it wasn’t stopped at customs neither a cent of taxes was claimed. delivery was average to fast (2weeks) but I must mention fast shipping, seller did it within one day which is a kind of unicorn among the Aliexpress sellers, especially just before the Lunar new year.
So far so good. Have used now for a couple hundred kilometres on the trainer. Shifting is pretty good although the front derailleur is challenging to set and the cable routing is fairly rudimentary which puts more stress on the shifter. Will see how it lasts - others have reported problems with a broken part in the front shifter due to the high cable tension
