Axiom

Thompson Expandable Seat Bag Black and Carbon

Great. Good look and fits my cable lock, wallet, keys and phone. Deceivingly spacey but also neat.

I bought this bag for my road bike, it clips to a bracket that mounts to the seat rails which makes it really easy to pull off when adjusting saddle position, i'm using the saddle demo program from Tree Fort and making a lot of adjustments right now. I had purchased an Axiom trunk bag for my wife about 5 years ago and she has used it on her bike as well as everyday for a lunch/book bag for work and it has almost no signs of wear which tells me it is quality! There is more room than i thought and I haven't found it necessary to expand. Also the bag zips around the rear and the mount holds it sturdy for one handed opening and closing which is very handy.

I really liked the clip mounting to the seat so the bag comes off quickly and easily.
