I have had this bag for several months. The strap that is supposed go around the seat post does not reach on my aero seat post.
I had mickey moused that strap to go under the seat. The bag hung funny when I did that and worked for a while. Eventually because it was
not well 2 of the 3 straps came undone and the bag was flopping all over the place.
I would like to just purchase a good secure saddle bag that was meant to attach to an aero seat post or a saddle bag that does not require it.
