The third generation of Noah Fast aero technology enters the gravel segment, with frame improvements designed to offset the aerodynamic penalty of wider tyres.
The Kanzo Fast 2.0 brings Ridley’s third-generation aero technology from the Noah Fast into the gravel segment. The frame’s aerodynamic development is specifically tuned to accommodate the larger tyre volumes required by modern gravel racing. Wider tyres typically create additional aerodynamic drag, but the optimised frame shapes are designed to offset this loss in aerodynamic efficiency. This allows the Kanzo Fast 2.0 to combine the performance benefits of wider tyres with the speed of a highly aerodynamic race bike. The result is a gravel platform that remains efficient even at high speeds.

Up to 58 mm of tyre clearance gives riders maximum freedom to choose the optimal tyre setup for every course and condition.
The Kanzo Fast 2.0 offers clearance for tyres up to 58 mm, equivalent to a 29 × 2.3” MTB tyre. This gives gravel racers the freedom to adapt their tyre choice to the course, surface and conditions. High-volume tyres can provide tangible advantages on rough gravel, including increased traction, improved comfort and lower rolling resistance. Riders opting for narrower tyres also benefit from generous mud clearance, which can be particularly valuable in wet and technical races. Rather than being designed around a single tyre size, the Kanzo Fast 2.0 provides a race platform that can be adapted to the demands of every course.

The Ridley Kanzo Fast 2.0 was recognised by leading cycling platform BikeRadar and praised as a bike that “defines everything the modern gravel bike should be.”
The Ridley Kanzo Fast 2.0 was recognised by leading cycling platform BikeRadar and praised as a bike that “defines everything the modern gravel bike should be.” Its combination of speed, aerodynamics, control and versatility makes the Kanzo Fast 2.0 a gravel bike ready for any challenge. A modern gravel bike, recognised by one of the world’s leading cycling platforms.

Race-bred performance meets the versatility required by real-world gravel riding.
The Kanzo Fast 2.0 is designed for more than dry race days. Integrated top tube mounts allow riders to add a low-profile top tube bag, while compatibility with Ridley’s bespoke Curana mudguard system makes the bike suitable for winter training and wet-weather riding. Combined with its wide tyre clearance, the Kanzo Fast 2.0 can be adapted to a wide range of conditions without compromising its racing DNA.

Integrated storage keeps essential items safely inside the frame without compromising the clean, aerodynamic lines of the Kanzo Fast 2.0.
The Kanzo Fast 2.0 features a discreet storage compartment inside the downtube, providing space for essentials such as a CO₂ cartridge, multitool or spare tube. A robust cover keeps the contents securely in place without disturbing the aerodynamic shape of the frame. The bike comes with two padded storage pouches in different sizes, allowing riders to adapt their loadout to the needs of each ride or race. Both pouches can be used individually or together. Their padding also helps minimise unwanted rattling sounds while riding.
