I have never seen that before, I can't fathom why anyone would do that. As an aside there wasn't an airpump on the bike either.
Any thoughts?
One of my bikes has a presta rim and a schrader rim. I did go the extra mile and got a grommet to put into the schrader rim so I could run 2 presta tubes. But I could have as easily had mixed tubes to go w/ the mixed rims.
I have a coworker who runs presta tubes in schrader rims w/ no ill effects (yet), and another who had a big explosion when the base of a presta tube pushed through the hole for a schrader rim.
