Could be wrong here, but I was under the impression that quite a few frame pumps had the capability to work with both Schraeder and Presta by fiddling with the pump head guts. Also, you didn't have to buy new tubes- you could've just gotten an adapter for the valve stems.

And you may not 'need' stronger wheels- just make sure the ones you got are both true and tensioned properly.

Other than that, good for you! I've been walking the last two days due to mechanical issues
