Ridley is moving toward the production release of its second-generation aero gravel racer, tentatively named the Kanzo Fast 2.0. Spotted at Eurobike 2026, the prototype indicates a shift toward massive tire clearance, integrated frame storage, and progressive geometry designed to optimize rider aerodynamics. The bike marks a departure from earlier test mules, moving from experimental components to refined, production-ready features.
Why is tire clearance becoming the centerpiece of aero gravel design?
The new Ridley Kanzo Fast 2.0 features an official maximum tire clearance of 58mm, according to representatives at the Ridley Eurobike booth. This design choice signals a broader industry trend where manufacturers prioritize high-volume tires to manage rough terrain while using frame shaping to mitigate the resulting aerodynamic drag. By comparison, while the 3T Exploro pioneered aero gravel shapes, Ridley’s latest approach integrates deep head tube profiles and a seat tube that contours tightly to the rear wheel to shield the tires from the wind. This focus on “system aero”—where the frame is shaped specifically to protect the widest possible rubber—represents a shift from traditional road-derived aero profiles.

The Ridley Kanzo Fast 2.0 utilizes a specialized Wolf Tooth chain guide. According to Ridley, this component was co-developed specifically for this frame to maintain drivetrain efficiency and airflow while supporting 1x gearing setups.
How does modern progressive geometry improve gravel performance?
Ridley has adopted a progressive geometry for the Kanzo Fast 2.0, characterized by a steeper seat tube angle combined with a longer top tube and shorter stem. According to company sources, this setup serves a functional aerodynamic purpose: it opens the rider’s hip angle. By allowing the rider to maintain a more aggressive, lower position without sacrificing power output, the bike aims to reduce the total aerodynamic profile of the bike-and-rider system. This geometry shift mirrors recent trends in elite-level gravel racing, where maintaining a sustained aero tuck over long, flat sections is as critical as handling stability on technical descents.
What are the primary updates in frame integration?
The Kanzo Fast 2.0 introduces in-frame storage, a feature absent from its predecessor. A small opening located beneath the bottle mount allows for internal storage, a design choice intended to keep the bike’s center of gravity low and its exterior surface smooth. Additionally, the frame includes protected top tube mounts for further gear capacity. These updates highlight a move away from external, wind-catching bags toward internal solutions that preserve the frame’s aerodynamic integrity, a design priority noted during the bike’s development phase.
Pro Tip: Optimizing Your Gravel Setup
When choosing tires for wide-clearance frames, look for rim widths that match your tire volume. As noted by Ridley staff, the unreleased Forza Skiron RS wheels on the prototype feature carbon spokes and a wide internal profile, which prevents “lightbulbing”—the unstable, bulbous shape a tire takes when mounted on a rim that is too narrow for its width.

Frequently Asked Questions
- When will the Ridley Kanzo Fast 2.0 be available?
Ridley representatives state that further details and a full release are expected by late summer or early fall 2026. - Does the new Kanzo support a front derailleur?
While the frame includes a mount that appears capable of managing a front derailleur, Ridley reports that the stock configuration is intended for 1x drivetrains. - What is the maximum tire size for the Kanzo Fast 2.0?
The official maximum tire clearance is 58mm.
