I am about to buy 2 new tires and tubes. My current ones are Presta valves. I'm ignorant about this, so can I get Schrader valves on my new tubes and be set, or is there more to it than that?
The valve holes in your rims might not be large enough.
Agree, they are definitely not large enough if the bike came with Presta originally. Nothing a drill and 5 minutes can't fix.
I did that on a mountain bike once. It worked fine.
But the rims on a MTB are large enough, and I prefer filling those up with a motorized (ie gas station) pump as well.
