Specialized Roll Sport Bike

The Roll is made of our A1 Premium Aluminum, and it features our Ground Control Positioning that makes it easy to put a foot down when stopped. This Roll also comes ready with rack/fender mounts. Wide diameter, 650b x 2.3" Nimbus II Sport tires provide excellent traction, stability, and cushioning, which creates a safer, more reliable, and more comfortable ride on either paved or dirt roads. Plus, the reflective accents of the tire increase your visibility to motorists in low-light conditions. Equipped with our Body Geometry "The Cup" saddle, you can expect a supreme level of comfort anywhere you take the Roll. It delivers on these expectations by "cupping" your sit bones, which reduces pressure without feeling obtrusive or constraining.\
