Have the bag tinkered on my touring bike; Ruck Zuck and went with the Velcro straps that are not in this case far too long, they still cling to the frame. My castle chain with 2.2 kg, 120 cm length fits in comfortably. The processing of the bag is good quality and the zippers work stable. Products without flaw and with high practical benefits of getting me 5 stars.
