Kanzo Fast GRX800 1x KAF01Bs(M)
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!
Ditch the front derailleur! Maximum power transfer, aerodynamics and yet room for wide 42mm tires in a short chainstay are the result.
Thanks to a D-shaped steerer tube, we can fully integrate all cables. A huge aerodynamic advantage that looks so sleek!
The Essential Series of Ridley bikes uses exceptional carbon by Toray, taking key features of the Elite Series to a more affordable level.
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.
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 incorporate the unique, aerodynamic Ridley tube shape that lets you ride much faster, without pedaling harder.
Geometries based on gender are outdated. Everyone is unique! Ridley recommends bike-fitting and a custom build with our Ridley Configurator.
By designing a seatpost as D-shaped, rather than round, you significantly increase its aerodynamics and comfort. A win-win result!
Ridley developed seatstays using oval tubes. The result is maximized comfort and perfected power transfer!
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.
