This shouldnt be a big deal. There is the special collar that fits in the shrader sized hole that allowes you to use presta tubes. My LBS carries them, and I would think that most good shops should carrry them.

BTW my RANS Stratus came with them, and I carry one just to make sure that if somehow I lost one on the road, I would have a spare. I actually think they are a good deal since the tube side of this aluminium gromet is curved inside so the stem is well supported rather than just a square hole for the stem.
