They say that every journey begins with a single step, but when that journey is related to exercise, that first step can sure be a doozy. It can be life-changing, however, and there's no better machine to take the plunge with than with the Roll. With its lightweight alloy frame and fork, a low-entry frame that lets you easily put a foot down when needed, nine speeds of "go fast" Shimano gearing, stable and wide 650b tires, powerful Shimano hydraulic disc brakes, and low-entry design that makes it a easier to get on and off the bike, the Roll does everything in its power to encourage and motivate you to keep fit and get around in comfortable, efficient style.
- The Low-Entry Roll is made from 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 mount, making it easy to carry extra weight.
- Wide diameter, 650b x 2.3" Nimbus II Sport Reflect 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 a Body Geometry "The Cup" saddle, you can expect a supreme level of comfort anywhere you ridel. It delivers on these expectations by "cupping" your sit bones, which reduces pressure without feeling obtrusive or constraining.
