29-Inch

Serfas' Drifter is a great tire for cruising down the bike path and rolling down city streets. The tough 69 durometer rubber maximizes mileage while the inverted tread reduces rolling resistance for efficiency on the road. Plus, Serfas' Flat-Protection System lets you ride worry-free.

Serfas' Krest folding bead tire will tackle all terrain—hard pack, loose dirt, and mud. Ramped, medium-height knobs in the center offer speed, while tightly spaced lugs all around provide constant traction. It also features Serfas' FPS technology for flat protection.
