The frame uses Toray T800 carbon to add stiffness and T700 to allow flexibility in key areas, giving comfort where needed. Designed using CFD aerodynamics (Computational Fluid Dynamics) not just wind tunnel testing, the latest research has shown the truncated foil design allows air to move around the frame from any angle as efficiently as possible. This means aerodynamics in real world situations, not just in wind tunnels.
The rear stays have been redesigned for additional comfort and improved braking, allowing clearance for up to 28mm tyres. Disc brakes use the flat mount standard for hydraulic or mechanical calipers and thru-axles keep everything stiff and secure.
