About Kanzo Fast

The first step in creating the Kanzo Fast was to pair the aero features and sublime power transfer of the Noah Fast Disc with our Kanzo gravel knowledge. Next our Ridley engineers spent hours in the wind tunnel and on gravel roads for further development and testing. What we created in the end was the perfect, aerodynamic gravel bike to win gravel races! Its geometry and aero handlebars are designed entirely according to the gravel standard.

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, we set the seat stays extra low and used the vibration-damping D-shaped seatpost. Aerodynamic, yet comfortable!

Start configuration


1x Only Kanzo Fast

Ditch the front derailleur! Maximum power transfer, aerodynamics and yet room for wide 42mm tires in a short chainstay are the result.

Best Gravel Race Bike of 2023

Gran Fondo Cycling Magazin named our Kanzo Fast the best gravel road bike of 2023.

Ridley Elite Carbon

We use a combination of the very best Torayca carbon: 60T, 50T, 30T, 24T. Toray carbon gives these Ridleys an exceptional cycling feel.

Women-specific Bikes

Geometries based on gender are outdated. Everyone is unique! Ridley recommends bike-fitting and a custom build with our Ridley Configurator.

Kanzo Fast tubing

The Kanzo Fast lets you tear across any surface as quickly as possible. This is due to meticulous attention paid to each aspect of it.

Kanzo Fast Aero Handlebar

An aerodynamic gravel handlebar? It may seem like an impossible combination, until you try the incredibly aero Kanzo Fast handlebar!


A wheel hub causes turbulence. The F-Wings streamline that turbulent wind. Maybe a small detail, but it instantly makes you a faster rider!

F-Tubing & F-Surface Plus

F-Tubing & F-Surface Plus incorporate the unique, aerodynamic Ridley tube shape that lets you ride much faster, without pedaling harder.


Thanks to a D-shaped steerer tube, we can fully integrate all cables. A huge aerodynamic advantage that looks so sleek!

D-shaped Seatpost

By designing a seatpost as D-shaped, rather than round, you significantly increase its aerodynamics and comfort. A win-win result!

Comfort seatstays

Ridley developed seatstays using oval tubes. The result is maximized comfort and perfected power transfer!

Kanzo Specific Tire Clearance

Each Kanzo model has a tire clearance that is optimised for a specific use and terrain.

Mudguard Mounts

The frame and fork has fixing mounts for mudguards.

About the Kanzo Fast family

The Kanzo Fast gravel bikes are lightning fast on any terrain. Their effective power transfer helps you convert every single watt into maximum speed. They are also expert at cutting through wind while keeping you comfortable to ensure that you can confidently go the distance. A fine piece of engineering that will have you flying – no matter the terrain or weather conditions!

Designed with a focus on aerodynamics and gravel, each tube has an optimized NACA profile. To ensure that aerodynamics is on point, the bikes were extensively tested in our wind tunnel. Our engineers also ensured for a hefty chunk of comfort. The Kanzo Fast gravel bikes have a lowered seat stay for vertical compliance, comfortable seatpost and true gravel geometry.
