Ridley Kanzo Fast GRX Carbon Gravel Bike - 2023
The first step in creating the Kanzo Fast was to pair the aero features and sublime power transfer of the Noah Fast Disc with Ridley's Kanzo gravel knowledge. The engineers at Ridley spent hours in the wind tunnel and on gravel roads for further R&D testing. What they created was the perfect, aerodynamic gravel bike to win races! 
No gravel bike is as responsive as the Kanzo Fast. It combines NACA profiles with a very stiff bottom bracket to propel you forward with every pedal stroke. To ensure for optimal comfort, Ridley have set extra low seat stays and used the vibration-damping D-shaped seatpost. Aerodynamic, yet comfortable!
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 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.
Ridley’s new 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. Compatible with Shimano, Campagnolo and SRAM. 
Kanzo Fast tubing
The Kanzo Fast contains lots of exceptional technology such as F-Tubing, F-Wings, lowered seat stays, D-shaped seatpost. Another remarkable feature is its seamless integration of fork and handlebar with the frame. Most developers thoroughly test each part for aerodynamics, but forget to test the bike as a whole. Ridley's testing method, in contrast, ensures that all aspects of the bike are tested as well as the perfect integration of all essential components. In addition, the massive bottom bracket and dropped chain stays play an important role in converting every watt into maximum speed. You'll feel it from the very first pedal stroke, and especially when getting back up to speed after every turn.
Mudguard Mounts
The frame and fork have mounts to assemble mudguards to protect you against the rain and dirt of the road. The mudguards will convert your bike in a perfect winter bike or commuter bike.
