Description

When being fast just isn’t fast enough, the ULTRA-AERO SL steps up. Faster in the wind tunnel and quicker on the road, it’s built to cut through the air and turn every ride into a chance to push the pace. This setup pairs the smooth reliability of Shimano 105 12-speed mechanical shifting with lightweight Mavic Ksyrium 30 alloy wheels, fast-rolling Pirelli P Zero Road tyres and a unisex Selle Italia Model X Superflow saddle for balanced speed and comfort. The integrated aerodynamic carbon cockpit completes a package designed to keep you moving quickly and with maximum efficiency.

Groupset

Shimano’s first and only 12-speed mechanical groupset is the latest addition to the premium road family. 105 7100 combines pure cycling with pure craftmanship. Inspired by 105 Di2, this versatile drivetrain delivers the wide gear range, hand-friendly ergonomics and all-condition braking confidence you’ve always craved. Developed from Shimano’s Science of Speed philosophy, 105 mechanical raises accessible performance to a whole new level.

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.

* Image for illustrative purposes only. The RI-2 replaces the LEVEL 5 handlebar and features updated graphics and a revised aesthetic.

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.
