Bought a new cycle pump after my Topeak mini rocket died. In all fairness probably due to water ingress via the handle, I should have mounted it upside down to alleviate that problem. I was on the lookout for something a bit cheaper but still well made when I came across a Rolson pump in QD of all places for £5.00. I looked at the Rolson website and saw that it would pump up to 120 psi. So for the sake of a fiver I bought it and just had to test it. I let down one of my tyres and started to pump it up again. The valve connector fits snugly and not once did it loosen it`s grip. It soon got the tyre pumped up again, with quite a few pumps, being so small, that is the trade off I suppose. The only other downside is that you have to be careful that you don`t jamb your hand which is holding the valve straight. For £5.00 it looks well made, only time will tell. Just one other thing, that is most of these type of pumps are bought ready for a schneider valve so you have to unscrew the adapter and turn the inside around.
