We don’t say this lightly: since occasional flats are inevitable and would otherwise leave cyclists stranded, virtually everybody who bikes long distances needs a portable pump. And as it turns out, there’s no need to stash one in your pack or on the frame, since your bike likely sports a storage compartment for one already: the hollow Shimano axle between your cranks. CrankPump makes full use of this space, screwing in to replace the standard axle cover. When a flat occurs, just unscrew CrankPump, remove and use the red and blue TireZip levers to unzip the tire, then inflate the new tube using CrankPump’s CO2 canister to 90 PSI – more than enough to head home.
