I bought this bag but I find that I am preferring my backpack. I paid about $120 after tax and s/h.
The bag is like new, including the original box and a full extra set of mounting straps, so you can set it up on multiple bikes. I have 8 straps and 7 buckles total, only 4 of the buckles and 2 straps have actually been used.
Asking $90, buyer pays s/h
