I definitely do not recommend the site. To do was repair the drive. On receiving the main reason for the repair was not removed. Despite two corrections on the spot, it was necessary to leave the bicycle for repair for one day. The end result was not satisfactory, but I was quite correct and driving, this is where I would give 3 stars. Unfortunately, after a relatively small operation (approx. 100 km) drive problems returned to a state worse than before the renovation. So it was a lot of money thrown down the drain.

After the complaint, the service is at a high level. I also appreciate the professional approach to the customer. Only the whole process took quite a long time. Nevertheless, the end result pleasantly surprised me, so give 4 stars.
