2021 Specialized Roll Sport Low-Entry Bicycle. This is a great bike for Trilogy! Equally at home on the trails or street, the Roll Sport has excellent performance all around. Front and rear disk brakes and 21 speeds let's you tackle any terrain with confidence. The Specialized Low-Entry frame makes the bike very easy to mount/dismount without sacrificing strength. It is a size Large, which should fit folks from about 5'8" to 6'2". I purchased this bike new but was only able to enjoy it for a short period of time due to a progressive neuromuscular disease. It has very few miles on it and it is in almost new condition. I paid $800 + tax, asking $400.

Product Details
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.
• 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.
