Hi there. To be honest I've not tried that yet as I've mainly used it as a shock pump but will investigate over the weekend and get back to you. Thanks for watching.

i have the 2 stage track pump , so yes , under high vol mode the efficiency tops at 30 psi and then you gotta change to High pressure

Hi there! The release valve is VERY sensitive so holding the pump without touching it to pump up definitely has a technique to it. Also finding as it's sensitive you have to touch very lightly to release air to a required amount. I've been going way above what I need then releasing it down to what I need. Just need more practice tbh. Hope this helps? Thank you for watching!

@@ryandodgeshaw thanks a lot. What about unscrewing it after pumping a shock? Other Topeak has a nice system to avoid air leak Its not clear on this one.

@@willygoncalves2219 Yes I forgot to add, you undo the black part first then the valve part. Thanks for reminding me.

Thanks! Bought the same one, mine is basically impossible to unscrew the black part when doing the rear shock around 260psi. Do you have a similar problem?

@@ryandodgeshaw what are the steps to disconnect, is air lost when disconnecting?

Hi there. This was mainly an unboxing edit to be honest.
