Ultra Aero SL R Shimano Ultegra Di2 12 Speed Carbon Aero Road Bike Ultra

An ULTRA series carbon bike built around one objective: helping riders convert more of their effort into forward speed. Developed through CFD analysis, wind tunnel testing and real-world validation, the ULTRA-AERO SL R uses advanced aerodynamic tube shaping, integrated component design and a race-focused geometry to reduce drag and maintain momentum when the pace is high. The lightweight carbon frame delivers the stiffness and responsiveness needed for hard accelerations and fast riding, while retaining the confidence and control required for long days in the saddle. Shimano Ultegra Di2 electronic shifting, Mavic Cosmic S 42 carbon wheels, Vittoria Corsa N.EXT 30 mm tyres, the ULTRA-AERO integrated carbon cockpit and a Selle Italia SLR Advan Superflow saddle elevate the ride with greater efficiency, responsiveness and refinement.
