A fast-rolling center section, flexible shoulder lugs and fine sipes give Continental's Contact II tire great grip on varied terrain. It also boasts Continental's SafetySystem for exceptional puncture protection with little added weight.

Continental's Cyclocross Race delivers tubular-like feel with a large-volume 35mm casing. So forget about dealing with glue and run the Race at lower pressure for that perfect balance between traction, comfort and low-rolling resistance. It's a great all-around tire: train on it, commute on it, race on it.

The name Airstop says it all. Michelin's Airstop tubes use a proprietary butyl rubber so your tires keep their pressure longer. And, the reinforced valve stem seam is ultra sturdy, too. - Weight: 128 grams (Schrader valve)
