    The set is as described, but it arrived in a somewhat adventurous packaging. . . The components themselves feel high-quality. . . The buttons and knobs feel good and are similar in feel to the branded parts. . . The braking feel is good. . . . The rear derailleur shifts cleanly and can be adjusted easily and quickly. . . However, the front derailleur is causing me problems. . . It’s really not easy to adjust. . . . The space between the frame and the limit area is too small, so I have to work with spacers. . . In addition, the trimming function is very poorly implemented. . . . It is possible to manually adjust the turner a bit, but that only works in one direction. . . Unfortunately, it is not possible to return to the original positions. . You then have to change the chainring first. . .
    and switch it back so that the chain doesn’t wear out
    Considering the price, I’m actually satisfied, but I wouldn’t buy it again and would rather invest a little more next time.
