I'd like to get a very small seat bag for my Brooks B17 - something large enough to hold a tube, cartridges, minimal necessary tools and that's it. I want it, however, to use the bag loops on the seat and not the rails (for some reason, that's more appealing to me). I've only been able to find bags that are significantly wider than my brooks that use the bag loops - nothing in the same size/shape as the typical underseat bag one would find on a road bike. This obviously won't be my only bag, but when I use my bike for club rides, etc., it would be nice to have the smaller one. I don't really care for the Brooks bags (and they're all of the "wider" variety so far as I can tell).
Thanks. Jim Harvey
