Possibly the most compact pump around, the Nashbar Mini Frame Pump is mini only in size and weight. A slightly broader cylinder gives plenty of volume for quick inflation. Plus a hi-volume/hi-pressure switch on the bottom allows you to put the finishing pounds into your tire with ease. Just attach the mount underneath your water bottle cage and snap it in...and say goodbye to hitching a ride home.
Tough alloy construction is light as well
Hi-vol/Hi-pressure switch lets you get most of the air in quickly, and then put those last few pounds in without killing your arms
Mount attaches under bottle cage/pump sits along side bottle
