I was having trouble inflating the Presta x Tubolito tubes on my Brompton, so I decided to treat myself to a new track pump.
The Lezyne pump on the Brompton website was competitive priced and I assumed that the pump would be set up for their bikes.
I was somewhat taken aback to find that the valve head was screw based, as opposed to a clamp system, but I persevered.
It quickly came apparent that was totally useless as the twisting head is far, far too tight even after a spot of chain lubricant, certainly nowhere near the easily twisting head depicted on Lezyne's website. As a result as one tries to screw the head onto the valve, it tends to screw the Presta cap back shut which is extremely frustrating.
I contacted Lezyne who suggested clamping the head in the chuck of an electric drill and using the drill to run it in and thus loosen the head !!!!!
In conclusion, may I suggest that a Brompton staff member tries this head on their bikes ????
