im very frustrated. ive got a 2.5 lb in a bracket in front of the rear tire, but i wanted to keep a.....spare.... yea... a spare bottle in the plastics somewhere....you know.. just in case. a 1lb wont fit. i had enough trouble just getting my air shifter bottle in the tailsection. i picked up an ebay tailsection/light pod that was scuffed up, im working on molding the pods into the tailsection for a cleaner look, as well as making (hopefully) enough room for a sneaky pete bottle on the way. i may have to switch to a genI... and i dont wanna.
