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. The Roll Sport has everything you need to help achieve your goals, like a wide range of Shimano gears, a comfortable, upright geometry, wide and grippy 650b tires, hassle-free mechanical disc brakes, and a whole host of other components that are built to withstand years of riding. You don't have to sacrifice—you just need the Roll Sport.

  • The 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 tires provide excellent traction, stability, and cushioning, which creates a safer, more reliable, and more comfortable ride on either paved or dirt roads.
  • 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.
