Ribble Ultra-Aero SL R Shimano Dura-Ace Di2 12-Speed - Carbon Aero Road Bike

An ULTRA series carbon bike built around one objective: helping riders convert more of their effort into free speed. Developed using 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's flagship Dura-Ace Di2 groupset, Mavic Cosmic SL 45 carbon wheels, Vittoria Corsa N.EXT 30 mm tyres, the Ultra-Aero integrated carbon cockpit and a Selle Italia SLR Carbon Superflow saddle combine to create a no-compromise build for riders seeking every possible performance advantage.
