Ultra-Aero SL - Pro
Lightweight aero carbon frame, forks & bars. Shimano Ultegra Di2 for lightweight electronic shifting.
ULTRA-AERO SL
When being fast just isn’t fast enough! Faster in the wind tunnel and faster on the road, the ULTRA-AERO SL is designed to dominate, defeat the wind, and make your fastest rides even faster.
Aerodynamic Performance
Ride faster with a frame engineered to minimise drag in real-world conditions. The ULTRA-AERO SL has been refined around the crosswinds riders actually face, delivering proven aerodynamic gains that translate into measurable time savings over race distances.
Aero Frame Design
Hold speed with tube profiles developed through CFD, wind tunnel and real-world testing. The frame, fork and seatpost work as a unified aerodynamic system, optimised to manage airflow across a wide range of yaw angles for maximum efficiency.
Aero-Optimised Downtube
Maintain speed with a downtube shaped to work with your bottle, not against it. The flared lower section improves airflow while increasing stiffness around the bottom bracket for efficient power transfer under load.
Integrated Cockpit
A fully integrated cockpit keeps airflow uninterrupted across the front of the bike. The RI-2 carbon bar and stem hides every cable while creating a stiff, aerodynamic platform built for speed.
Aero Rear-End Design
Reduce drag across the rear of the bike with a truncated airfoil seat tube and aerodynamically shaped seat stays that closely follow the rear wheel. This design smooths airflow behind the rider while maintaining excellent lateral stiffness.
An Aero Obsession
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.
