Nappo (Diamant 135) is based on the Trek 520 Disc. Basically it is the same bicycle just with different parts. So far I am very happy with with him, he has a steel frame and the racks (front and back) are very nice and carry my bags stable. 

​

After 4500 kms I had to change the pedals and the tyres and my frame (the "bottle holder pen" which hold the bottle holder) broke, which means that my frame had a crack. I had to weld it, now everything is fine again.

​

Even though I like Nappo very much, if I had to buy a new bike I wouldn't buy it again.
