2021 Specialized Roll Sport - Low-Entry Features
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. But that one step, or in our case pedal stroke, can be life-changing—and there's no better machine to take the plunge with than with the Roll.
It has everything you need to help achieve your goals, like a comfortable and upright geometry that makes getting on and off the bike super easy, wide and grippy 650b tires, hassle-free mechanical disc brakes, and a big mix of Shimano components that are built to withstand years of riding. You don't have to sacrifice, you just need the Roll Sport Low-Entry.
At a Glance
- The Low-Entry Roll is made of our A1 Premium Aluminum. It features our Ground Control Positioning that makes it easy to put a foot down when stopped, while our Low-Entry design makes getting on and off a breeze. Lastly, the frame 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.
