I'm about to buy a new rear tire, specifically, the Panaracer XC pro 2.1. The tire has a listing as a kevlar tire: http://www.rei.com/product/661232?st...Id=40000008000 and as a foldable tire: http://www.rei.com/product/784483?st...Id=40000008000. Are these actually different? There is also the wire bead version, which I'm not interested in.

Thanks for the help!
