I have one of these shock pumps, very good bit of kit.
Used it on Fox forks & shocks as well as Rockshox forks & Manitou shocks.
It will work well if you need a highish pressure (50psi+) in your shock/fork, if you only need a low pressure (<50psi) it's not gonna be very accurate, but will work.
Fits a standard Schrader valve BTW.
