Our tire size is about to down from 28 to 25 and it seams that 16gr CO2 cartridges will not be of much help if we have to repair a flat on the road (it wasn't great from the beginning but the 28 tires can run lower pressure).

I've been shopping but can't find anything satisfying: I want a pump that works well, will pump up to an actual 135psi and that will not offend my minimalist-CO2-cartridge-user's eyes.

Any recommendations?
