The new S5 uses deeper airfoil profiles and sharper trailing edges across the frame, fork, and cockpit to reduce drag and increase speed in real-world riding conditions. The head tube and fork feature extended chord lengths for improved airflow, while the redesigned cockpit and Reserve 57|64 wheels work together as a complete aero system.

The S5 is now 6.3w faster than the outgoing model and 8.7 watts over the nearest competitor. It’s speed you can feel, from the first pedal stroke to the finish line.

The redesigned HB19 cockpit takes everything riders loved about the previous S5 bar and makes it faster, sleeker, and more refined. A larger V-stem opening improves airflow through the front end, reducing drag and keeping the system clean and efficient at high speed.

The updated shaping also brings a narrower hood position, modernized drop ergonomics, and improved stability during sprints and hard cornering. Best of all, it’s fully backwards compatible, so your current S5 can upgrade to the latest performance

The S5 isn’t just fast on its own—it’s fast as a system. The new Reserve 57|64 wheels were developed alongside the frame, featuring deeper profiles and a cambered airfoil design that smooths airflow at high yaw angles. The asymmetric seat tube wraps around the rear wheel for a tighter, more aerodynamic interface, minimizing drag. Together, the frame and wheels work as one to reduce resistance, increase stiffness, and deliver maximum speed where it matters most—out on the road, not just in the wind tunnel.

The S5's handling has been refined around modern 29mm tires, with a 2mm lower bottom bracket that improves cornering confidence and lowers the center of gravity, while the increased fork offset sharpens steering response without compromising straight line speed. Best of all, the fit geometry remains unchanged—so you get all the handling benefits without having to rethink your position on the bike. It’s the same fit, with even better control.
