Love this pump. Hate the bracket. The worm gear screw snapped the back out of its hole. (okay, I overtightened it...)
Currently using 2 big velcro one-wrap straps to attach it to the underside of the top tube. I have a cable running along the top of the top tube, and I'm wrapping the velcro between the cable and the top tube so nothing gets interfered with.
Both my bottle cage mounts are populated with bottle cages.
Any other ideas? Or am I doing this the best I can? For now, I'm not interested in off-bike storage (backpack, etc)
