Hi there,

I just got my first mountain bike and have a question about tubes.

My road bike takes presta tubes. The frame pump I use does well with presta tubes, and does not seem to work well with the Schrader ones, even though it is advertised to work well with both.

Is there ANY reason to keep the Schrader tube in my mountain bike? Is there a durability issue? Are Schrader mtb tubes easier to buy if I'm stuck in the middle of nowhere with a flat and no extra tubes?

The wheel has a larger, Schrader sized tube opening. I'm told that a presta valve might 'move around' too much through that hole, but that it's easily correctable by screwing on a little adapter plug. In fact I already got the plugs from my bike shop.

Thanks!
