Description
When being fast just isn’t fast enough! Faster in the wind tunnel and quicker on the road, the ULTRA-AERO SL is designed to dominate, defeat the wind, and make your fastest rides even faster. In the Enthusiast specification, it's paired with Shimano's 105 Di2 electronic groupset, lightweight and dynamic Mavic Ksyrium 30 alloy wheels, Pirelli P Zero Road tyres, and unisex Selle Italia Model X Superflow saddle. The integrated aerodynamic carbon cockpit completes this race-ready package.
Groupset
Shimano 105 Di2 is the culmination of years of research and development. By combining technologies and functions inherited from Dura-Ace and Ultegra, 105 Di2 will transform your cycling experience. With a shared Di2 platform, sophisticated ergonomics, 105-optimised gear combinations and the exceptional stopping power of hydraulic disc brakes, Shimano 105 Di2 marks a new era of affordable performance. Di2 gives you the instant, lightning-fast gear shifts of the world’s fastest wireless groupset. At the push of a button – every time. Di2 is full of infinite possibilities. It allows you to embrace the freedom of the open road - and go deeper into the new day.
Wheelset
Ksyrium 30 Disc is the perfect entry point into high-level race performance. This tubeless-compatible wheelset's dynamic ride quality helps you roll faster and smoother while retaining a lightweight feel for climbing and accelerating. Paired with Pirelli P Zero road tyres, which balance performance with durability, for both reliability and grip. The carcass features excellent puncture resistance while keeping weight impressively low.
Handlebars
The Ribble RI-2 carbon integrated handlebar is a proprietary system that conceals every cable while providing optimal fit, adjustability, and seamless integration. This one-piece cockpit exemplifies the perfect marriage of form and function, combining a clean, cable-free aesthetic with advanced aerodynamics to reduce drag by up to 40% compared to a conventional handlebar setup. With a super-stiff carbon monocoque construction and refined ergonomics, the RI-2 system is designed for speed-conscious road riders who prioritise performance and all-day comfort.

Saddle
The ULTRA-AERO seat post features a truncated aerofoil profile that's aerodynamically optimised to reduce drag in the high-speed airflow disturbed by the rider's leg. A composite shaft absorbs road shocks for a vibration-smoothing ride quality further enhanced by a Selle Italia Model X saddle. Designed with sustainability in mind but without compromising performance, Model X features a glue-less assembly; with gel padding and a superflow cut-out for all-day ride comfort.
