I've been doing some searching about using presta tubes in schrader drilled rims. One thing i read was that the nut on Schwalbe tubes can be used as an adapter for schrader valves. I just happen to have some Schwalbe tubes and see the nut is stepped so that it will center in a schrader hole.
So.. when using the nut as an adapter.. does it go inside the rim? or outside like normal?
