1.0 out of 5 stars
Totally useless, 20 Oct. 2012
Simply put this is a terrible piece of equipment. No good for road bikes at all, it won't pump even close to the required pressures, doesn't attach sufficiently as the pump literally gets blown off when the pressure gets above 70. Even more frustrating is that when you get to a useable pressure and attaches to the valve (around 75psi) the release does not release the valve until its let out a substantial jet of air. I got this to deal with punctures on the road, thinking about it, it's probably easier to go home on flat tyres.
