This rack has passed with this unbeatable price all demands made by me with grade 1. I mounted it on a mountain bike. The universal mounting accessories can even the tricky MTB - frame construction to lead to a satisfactory result. The capacity must take account of the filigree overall structure. For the installation of two saddlebags to 15 per kg stability is insufficient. However, 10 kg baggage be handled without complaint. I recommend this product!
