Description
Born from extensive R&D, the ULTRA-AERO SL is designed for real-world aerodynamic performance. By optimising airflow between bike and rider, it delivers unmatched efficiency in everyday riding conditions. Rigorously tested against the Endurance SL R, a proven race-winning machine, the ULTRA-AERO SL is faster, lighter, and more refined—unlocking true performance gains. This isn’t just a pro-level aero bike—it’s for anyone chasing speed, efficiency, and the thrill of riding faster for less effort.
Now available as a frameset—designed for you to create your ultimate performance build.
Construction
Every inch of the frame, fork, and seat post is designed for pure speed. The fork seamlessly integrates with the head tube and handlebars, slicing through the wind to minimize drag across all angles. After extensive testing, we found the sweet spot: 68mm x 15mm fork blades—engineered to deliver serious aero gains from 5° and beyond. But here’s where it gets exciting—at 10° of YAW, the fork doesn’t just cut resistance; it creates thrust, turning the wind into an advantage and pushing you forward.
This isn’t just aerodynamics—it’s free speed.
Integration
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.
Ultra-Aero SL Seatpost
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.
