Topeak Super Chuck Dual Valve Pump Connector

I recommend this product

This is a solid piece of kit ,despite my summary I cant get the MTB valve to work , but as I never use it it doesn't matter.Takes a bit of practice to release from the valve but otherwise its OK

If you are pumping your tyres to 100 PSI pressure with a track pump, you will probably find the original pump head starting to hiss and pop off when it starts to wear after a year or two. If you can't get spares for it, this is the fix: it fits onto the usual thick walled hose easily with a clip. It's a quality solid brass item that you can get a spare rubber seal for.
It's really for Presta valves, but there is a schrader adapter included.
There is similar one from SKS, but I haven't seen it: it can't be better but it's cheaper.

I got just what I ordered, for the money they said and received it when they said I would!

Brilliant service . . . if SJS did lager it would probably be the best . . . PROBABLY!!!!
