Description
The ULTRA-AERO SL R results from doing something that has never been done before. It guarantees gains never seen on a road bike and is aerodynamically optimised to make your fastest rides even faster. In Sport specification, it's paired with Shimano's 105 Di2 electronic groupset, lightweight and dynamic Ksyrium 30 alloy wheels, Pirelli P Zero Road tyres, and a unisex Selle Italia Model X Superflow saddle. The ground-breaking Ultra 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 road 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 performance, making accurate, lightning-fast, and reliable electronic gear shifting more accessible to all.
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 for grip, comfort, and puncture protection, this setup strikes the perfect balance between speed and durability, whatever the road ahead.
Handlebars
Engineered for pure speed, the ULTRA-AERO bars are purpose-built for our fastest-ever aero bike. Their patented, next-generation design introduces a revolutionary wake-generating concept that reshapes airflow, creating a controlled pocket for the rider’s legs to sit within and reducing drag where it matters most. The aggressive, wing-shaped tops slice the air with scalpel-like precision, while the ergonomic drops and flat-top section deliver comfort and control on long rides or steep climbs. A textured finish removes the need for bar tape, keeping things clean, fast, and uncompromisingly aerodynamic.
Saddle
Designed for pure aero performance, the ULTRA-AERO seatpost combines wind-cheating efficiency with real-world comfort. Its truncated aerofoil profile is shaped to cut through turbulent airflow behind the rider’s legs, helping you stay faster for longer. The composite shaft smooths out road buzz for a more refined ride feel, while the Selle Italia Model X saddle adds all-day comfort with its gel padding and Superflow cut-out. Built with a glue-less, sustainable design, it proves that performance and responsibility can go hand in hand.
