Description
Fast in the wind tunnel, faster on the road, the Ultra SL is designed to be ridden flat-out, all of the time. The serious racer or speed-obsessed road rider will appreciate the lightning-fast shifts of Shimano's latest wireless electronic 105 Di2 groupset complete with the exceptional braking control of hydraulic disc brakes. Aero-efficient Mavic Cosmic SL 45 carbon wheels matched with fast-rolling and grippy Pirelli P Zero Road tyres is a combination that delivers all-around performance on every terrain. A LEVEL 5 carbon integrated handlebar system with stealth cable routing preserves the jaw-dropping lines and reduces drag by up to 40% compared to a conventional handlebar setup.
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
Mavic Cosmic SL 45 wheels are engineered for riders seeking the perfect balance between weight, aerodynamics, and speed. Their minimal drag and low inertia design allows you to accelerate and climb faster, while holding higher speeds for longer. Paired with Pirelli P Zero Road tyres, which balance performance with durability, for both reliability and comfort. The carcass features excellent puncture resistance, whilst coming in at an impressively low weight.
Handlebars
The LEVEL 5 carbon integrated handlebar system takes cable integration to the next level. It allows every cable to be fully hidden within the frame for a clean, cable-free aesthetic and a drag reduction of up to 40% compared to a standard handlebar and stem setup. With a super-stiff carbon monocoque construction and all-day ergonomics, the LEVEL 5 system is ideal for the speed-conscious road rider with a taste for comfort and aiming to reach the podium's top step.
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.
