I just put a B-17 on my commuter bike, and hope to find a smallish tool bag that hangs from the saddle loops. I'm not crazy about the Brooks or Carradice bags, and they're spendy. I'd like something that could come off the bike easily when I lock up. I don't need leather or canvas.

Anybody know of a decent (maybe black) nylon bag that fastens with maybe fastex buckles to saddle loops, and would hold a tool or two, a road tube, and a CO2 cartridge? I don't need to carry a pound of tools or a tent...

TIA for any suggestions,

Mark
