Joe Blow Sport II
I'm not having any luck with pumps.
The connector on this thing lets out so much air during the connection and disconnection that I'd have to inflate my tyres to twice the recommended PSI just to have the max after disconnection.
I have Schrader valves and when connected air leaks through the coupling and out through the open Presta connection.
The issues I'm having with pumps is seriously getting me down.
