…that doesn’t loose any air when removed?
(have searched on here without success)

I know it should only be the air in the pump that is escaping as I’ve never had any problems with fox shocks, but trying different pressures on the SPV chamber on my Manitou 3ways just doesn’t seem to make any difference… though am now torn between getting another pump (this would be my 3rd), getting it serviced, **** it off for a fox….

Topeak do a two stage one!

I used to have a wrench force one that seemed pretty good, it had a micro adjust button to dial in the pressure.

any idea which model?

I’ve found this thing:

I can’t see how it would stop air-loss?
