The pull-out hose puts less stress on the valve. And you weren't stressed to start with. It's all very well hauling a giant pump around, but all that leverage can snap a delicate valve stem right off. Our presta-only head sits on a short pull out hose to give more options on where you pump from and fewer chances of your rippling muscles pulling the thing clean off. We weren't using that space in the barrel anyway, so the hose doesn't even affect the pump's efficiency.
Compact Design Why carry around more bulk than you have to? This product is designed for the minimalist in you.
Frame Mount Even the best pump won't do you much good if you've left it in your sock drawer at home. This pump comes with a discreet frame mount that attaches under your water bottle cage.
Flex Hose Don't be a slave to the valve. The flexible hose lets you work on the bike whether upright or dead on the trail while the secure cam-lock head ensures no nasty blowing off when you least expect it.
Presta Valve Tool Get loose on the trail. You can if you want, but your valves shouldn't. There's a handy, machined valve core tool right in the pump's base to keep everything snug.
Thread on pump head automatically adapts to Presta valves
