STD presta fitting on the majority of shocks and forks the exception being some ‘older Marz forks and old SID’s IIRC
All shock pump tend to be much of a muchness, though a long rubber hose is useful to fit awkward read shocks & some pumps have special ‘head’ to stop pressure losse on removal from the valve. Though I’m intrigued by these, as common knowledge is, the hiss of air you hear as you remove a pump is the air in the pump escaping, not from the fork or shock & any (small) ‘losses’ detected when you put the pump on, is just the pump being pressurised – so supposedly it’s just a gimic?
