Hi,
I was recently bought a Bikehut track pump, this one in fact ...
http://tinyurl.com/3d3btv
and it claims to have a 'clever valve' which will automatically adjust
to either presta or schrader through it's lever action.
It had no instructions printed on it's packaging and I can't figure
out how to get the lever action 'clever valve' to operate with my
presta valves. What happens is this:
1. I unscrew the dust cap and presta valve nut thing.
2. I offer up the 'clever valve' to the presta valve so that it is
'on' just far enough so that it doesn't press in the valve bit, i.e.
it is going to try to grip the narrow threaded bit.
3. I pull the lever to tighten the connection and let go.
4. The 'clever valve' pump bit falls off and onto the floor.
5. I decide that the pump connector wasn't 'on' far enough and offer
it up again, but this time I push it on a bit further.
6. All the air falls out of my tire :-(
7. I screw into place my presta->schrader adapter and pump up the
tire from flat.
Whilst using the adapter works, it is a PITA. I have tried unscrewing
the end of the 'clever valve' and turning around the rubber insert but
that doesn't seem to make any difference.
Can anyone help?
Thanks
Mike
