A retractable, thread-on hose coupled with a unique valve-tightening tool, and a sleek body to efficiently push air into your high-volume tires. The pull-out hose puts less stress on the valve. Our presta-only thread-on head sits on a short pull out hose to give more options on which position you pump from. Nervous about unthreading that valve when removing the pump? Enter one of the Core's awesome features: the Presta Valve Tool. Simply unthread the tool from the back of the pump and tighten your valve prior to threading the hose on. With a larger diameter barrel, this is a perfect pump to inflate your larger volume MTB tires without fuss.

FASTER INFLATION - The mid-size barrel diameter allows for quicker inflation on MTB, CX and gravel bikes.

PRESTA VALVE TOOL - Get loose on the trail. You can if you want, but your valves shouldn’t. There’s a machined Presta valve core tool right in the pump’s base to keep everything snug.

THREAD-ON DESIGN - Hold on tight. The thread-on Presta valve at the end of the extending flexible hose ensures that even the fiddliest of valves is held securely for inflation.

COMPACT DESIGN - Is that a pump in your pocket? Fits easily into a jersey pocket, but also will nestle unobtrusively next to your bottle cage so you’ll never leave home without it.
