In the several Presta tubes I bought for Brompton, half of the valves leaked. Just in case, I replaced those cores that did not leak too, just in case, not wanting to wait for a mishap at an importunate moment. DO NOT reuse cores from tubes that ran their life course. The cores have rubber seals that deteriorate with time, just like any rubber.
Not sure about the Hiro head but
Hirame, of which Hiro seems to be a copy, is certainly great. It also comes in the
Schrader version which is a good investment too.

Thanks both of you. Yes, the reputation of the Hiro is stellar. I'm tempted, very tempted. Also tempted to start using tyres with smooth valves, I hate that forcing it on feel. Thought, does anybody make half and half valves, bottom part threaded, top smooth?
Anyway, I saw this:
Hiro vs Hirame chucks.
I think I'd be using as in the Hirame example, as replacement for the current chuck. Is it not possible to do that with the Hiro? With a hose clamp or something?
Thanks.
