bought this to put on my spare bike so I can switch packs between the bikes. Like the one that came with the pack, it's not quite wide enough to fit on the upright part of the seat rails so it goes on the bottom/horizontal part of the rails. Problem with this is that the rear of the pack faces slightly downward, not straight back where you want your tail light faceing for max effectiveness. It's well constructed and stays put once you install it, no worries about the pack coming off. Wish it allowed some adjustment to point the attached pack in the right direction.
Wanted to move my topeak saddle bag from bike to bike without having to much hassle, this small piece makes that possible. Thank you!
Makes it simple to put my flat repair kit on all my bikes
What I like about the seat bag fixer is that it holds to the bottom of your seat rail securely, not like other bags that have velcro which wear and eventually break. My mistake was purchasing a smaller bag and the velcro came apart. I went back to my Topeak bag never to roam again!
Installed on new flat bar bike so I can rotate my seat bag bike to bike.
