[Closed] Silca Super Pista Chuck - leaking air

Hi,

Calling silca super pista track pump owners!

Bought one online recently and although its a nice bit of kit the chuck seems to be absolutely pants! Its a push on affair for the presta but is quite hard to get it in a position where it doesnt leak air? Also you have to unscrew this part to then screw on the schrader valve adapter which in itself is a pain in the arse, when unscrewing it leaks air but not sure if this is like a shock pump where its not actually leaking air its just releasing excess air from the pump or whatever.

Any suggestions, change the head or something to a smarthead?

cheers

Matt
