Is this suitable for french valves common to most road bikes?
I have been told portable pumps tend to bend the valves on road bikes. Is there any truth to this?
My last pump definitely tended to do this, but I believe it part to do with the manufacturing of the pump, and part to do with the speed with which you want to pump up your tube (if you're careful, you might avoid bending the valve stop).
That said, my last pump connected directly to the valve, and so the pumping action was directly transferred to the tube valve. The Topeak road pump has a flexible tube, and so there is some buffer between your pumping action and the valve. I would think this would alleviate almost all possibility of bending the tube valve.
