Can you use Presta instead of Schrader?
You can put a Presta-specific tube in a rim drilled for Schrader valves, but it’s not advisable for anything more than an emergency fix. Tubes and tires tend to move slightly on the rim. In the wider Schrader hole, a Presta can move around enough that the rim will actually cut the tube at the base of the valve.
