BUILT TO ORDER IN THE UK. DELIVERED IN UNDER A WEEK.
When being fast isn’t fast enough! Dominate the straight line, defeat the wind, and experience exhilaration like never before!
Ride faster with a handlebar engineered to control airflow around both bike and rider. The ULTRA-AERO cockpit uses wake-generating structures to create a Drag Reduction Zone, reducing resistance and delivering a proven 2.1% drag reduction compared to the already optimised RI-2 integrated cockpit.
A cleaner front end improves airflow and reduces drag. Stealth disc brake mounts position the calipers inboard of the fork profile, helping maintain smooth airflow across the front of the bike while preserving the clean aesthetic of a modern aero machine.
Maintain efficiency with tube shapes refined through CFD, wind tunnel and real-world testing. The extended headtube profile and flared downtube improve airflow across the frame while increasing stiffness around the bottom bracket for efficient power transfer.
Hold speed with a front end designed as a single aerodynamic system. The fork, headtube and handlebars work together to manage airflow across a wide range of yaw angles, delivering measurable aerodynamic gains in real-world crosswinds.
Reduce turbulence behind the rider with a truncated airfoil seat tube and aerodynamically shaped seat stays that follow the rear wheel profile. This design improves airflow across the rear of the bike while maintaining excellent lateral stiffness.
Watt-saving gains achieved across all areas of the frameset, the ULTRA-AERO SL R has been optimised to perform in real-world conditions, specifically around 5-10° of YAW, to simulate the crosswinds commonly experienced by a cyclist. Every aspect of this pioneering aero bike is engineered to slice through the air with class-leading efficiency and scalpel-like precision.
