Bottom line: if I had swept a little before the purchase or asked the owner in detail about the problems, I would never have bought this miracle of technology. Pros: In general, the kit is not bad. Wings were. Double suspension. Beautiful appearance. And. . everything. Has some cons: The front wheel of the box "eight". I ended up buying a new one. Switching gears is another quest. The chain is not always thrown to the extreme positions. And in general, the speeds are not always switched the first time - not a fountain in general. The rear brakes were not tuned out of the box: the disc rubs against one of the pads. After the first ten kilometers, a creak began, until it was possible to understand what exactly was creaking and how to fix it.
