Ridley Noah Disc 105 Carbon Road Bike - 2023

Ridley Noah Disc 105 Carbon Road Bike - 2023

The Noah is both a top aero bike as well as a continuously evolving technological masterpiece. Originally developed as the ultimate sprint bike for team Lotto, it has since incorporated all-round qualities. While it continues to win sprints, it now shines on the cobblestones around Roubaix as well.

Thanks to advanced aero-optimized technology combined with of in-depth wind tunnel testing, the Noah is world class in aerodynamics. All tubing, from fork to rear triangle, have an optimized NACA profile. Cables are cleverly integrated into the handlebar/stem. While the Noah may defy wind, it remains a lightweight road bike that's exceptionally comfortable. The Noah Disc has all the same technologies and ride qualities of its big brother, the Noah Fast Disc Caleb Ewan's favourite road bike, but is more budget-friendly.

Comfort Seatstays

The rear end of a bike is crucial for both adding comfort and maximizing power transfer. For added comfort, the seatstays are connected lower down on the seat tube. Due to this lower point of contact, both the seat tube and seatpost can more effectively filter out vibrations. In addition, the seatstays can provide more vertical flexibility. All this results in a more comfortable bike ride.

As for winning watts, the shape of the seatstays is oval with the widest side on the horizontal axis. This is key to maximizing power transfer. By placing this wide side horizontally, every watt produced is converted into speed, without losing power on the way to the rear wheel.

F-Steerer

Ridley’s F-Steerer, with half-moon curvature, ingeniously allows for fully internal cabling. Cables run straight from handlebar, through stem and directly inside the steerer tube where they have room to move freely as bar is turned from left to right. Not only does this decrease air friction from cable drag, but it gives your bike a very clean look. In addition, by adjusting the cross-section of the steerer, Ridley were able to increase its lateral stiffness, which comes in handy when sprinting.

Ridley Carbon

Ridley use only the best quality carbon available, sourced from Toray. They are the world’s leading carbon manufacturer, supplying mainly to the aerospace industry. The grades of high-modulus carbon Ridley use vary from the most pliable 24-ton, which gives the frame flex and comfort, to 60-ton which is the stiffest option.

F-Surface Plus

F-Surface Plus technology was created so you can convert the same watts into higher speeds. This technology is incorporated into Ridley’s Noah and Dean models. It is the application of a textured surface (similar to grooves in a golf ball) in strategic locations for decreased wind drag. What these grooves do is create a tiny turbulence which causes the main flow of air to better follow the shape of the tube. With a smooth air travel around the frame, you’ll expertly cut through wind. The stronger the wind, the more you will feel this technology working for you.

F-Tubing

F-Tubing is Ridley’s droplet-shaped tubing which significantly minimises wind drag. By shaping the tubes in such a way, airflow easily follows along the tubing. To further minimise tubing weight, hence increase speed per watt, Ridley blunt-cut the droplet shape just at the point where the airflow leaves the tubing. What this translates into is a drag differential of -4.03% at 50 km/h.
