Hi

I was just busy swapping my schrader valve tubes to presta valve ones. Got it nearly sorted, then realised, the hole in the wheel rim (the one the valve pokes through) is now way too big for the presta valve.

Is there any kind of nut or adapter I can use to sort this?
Any links or names of places I could buy them would be awesome!

Thanks, Will

In reply to CrankCrimp: I've used a mavic plastic adapter previously
which works fine looks like edinburgh cycles stock them

I use the little screw on ring as an adaptor, and screw it right down the valve body before fitting the tube, and it stops the metal around the hole cutting into the rubber.

It might not work on all rims though...
