The Ridley Kanzo Fast gravel bike delivers a robust riding experience across various terrains, including gravel and tarmac. This allows you to have a comfortable ride on any surface with maximum comfort and resilience to stress. 

The Kanzo Fast for 2022 features a Carbon 30T carbon frame and a fork with a 12mm thru-axle, providing the cycle with ultimate control across different terrain.

The bike’s frame also includes WTB Venture tires that provide robust grip on the ground regardless of weather conditions, although they do not offer the smoothest rolling resistance.

The bike has a higher stack and a shorter reach, providing efficient body shape and movement along the ride. The Ridley Kanzo Fast allows you to have a comfortable ride on the roughest patches.

The riding style can be adjusted as per the rider’s requirement. Including different sizes, the rider can adjust the components as per their requirements. 

The bike includes a Kanzo Fast Aero handlebar, which provides a proper grip and smooth aerodynamics, with hydraulic brakes and an 11-gear single chainset.

Ridley Kanzo Fast Gravel: Geometry

With the Kanzo Fast, Ridley welcomes in the rooster, an aerodynamic gravel bike with race-oriented geometry.

The frame is indeed based on the Noah Fast, Ridley’s aerodynamically optimized road bike,

With a few tweaks, the Belgian brand has adapted the design for gravel riding. The carbon frameset offers clearances for up to 700 x 42C tires and is compatible with the interesting Classified geared hub.

The bike’s competitive ambitions are ever-present aboard the Ridley Kanzo Fast, with an aggressive, stretched riding position.

The 168 mm long head tube, though, offers a tad of relief, allowing a relatively more relaxed rider position.

The transition between the fork and frame, the F-Wings at the bottom of the carbon fork, the fully integrated cable routing, the aerodynamic design, and the one-piece carbon cockpit are great features that place this bike in a different league.

Ridley offers plenty of customization and configuration options for the Kanzo Fast. All the groupset options you could imagine (for this league), plus 42 colors, and 7 designs. One downside, though, is that the frame is only compatible with 1x drivetrains.

The Kanzo Fast is a fast (indeed) and nimble gravel rig with a sporty feel balanced by the right dose of comfort.

Thanks to its compliance and the ability to absorb small bumps and high-frequency vibrations, it’s a comfortable gravel bike for long-distance rides on mixed terrains.

Although larger bumps and rocky roads are not its cup of tea, the Ridley always remains predictable, stable, and stiff.

The Ridley Kanzo is an extremely responsive bike with great acceleration and a flowing feel at moderate speeds.

Ridley Kanzo Fast GRX Specs

For our detailed component overview, we’ve chosen to analyze the GRX version among the many build options offered by Ridley.

Weighing in at 8.56 kg in size M, it comes with a 1×11 Shimano GRX RX815 Di2 groupset with Rotor ALDHU aero cranks, a Forza Vardar db wheelset, and Ridley’s Aero G1 cockpit.

Size compatibility is ensured at a component level by the different sizes available for the one-piece carbon cockpit and the proprietary Forza aero seat post.

The brake rotors are 160 mm front and just 140 mm at the rear, and it comes with WTB Venture Road TCS tires – not the smoothest and fastest tires.

Wrap Up

For speed-lovers and competitive souls, the Ridley Kanzo Fast, at the ambitious level, will deliver impressive performance on compact surfaces. Its stable handling and decent vibration-damping make it great for well-maintained gravel tracks, but it’s not enough to make it a proper off-road machine.

Overall, this is a great bike to go fast on tar and light gravel.
