Ridley
Kanzo AShimano GRX600 2x12sp
The Ridley Kanzo A is the brand’s long-running aluminum gravel platform, introduced in 2019 and carried forward with essentially the same frame and geometry. It sits at the practical end of the gravel market: a triple-butted, hydroformed 6061-T6 aluminum frame paired with a carbon Forza Oryx Disc fork, 12 mm thru-axles, and mounts that allow it to cover commuting, all-road riding, and light adventure use. Rather than chasing the latest extreme-clearance or ultra-progressive gravel trends, the Kanzo A is built around a more conservative, broadly usable concept.
What distinguishes it is that balance. With stated 700c tire clearance up to 42 mm and frame passport support for both 700c and 650B wheel setups, it is aimed more at mixed-surface riding and light bikepacking than at rough, modern expedition-style gravel riding. The geometry reflects that intent, prioritizing comfort and stability over aggressive handling. In the market, the Kanzo A fits as a budget-friendlier entry into drop-bar gravel riding for riders who want one bike to handle paved roads, hardpack, fenders, and day-to-day utility without the price or complexity of a carbon frame.

Geometry & fit.
6 sizes published.
The Kanzo A’s geometry is notably steady and conservative by current gravel standards. Head tube angles range from 70.0 degrees on the XXS to 71.5 degrees on the XL, with a consistent 430 mm chainstay across the size range and wheelbases from 1016 mm to 1066 mm. Those numbers point to stable, predictable steering rather than quick front-end response, especially when combined with the relatively generous stack figures: 528 mm on the XXS, 584 mm on the M, and 636 mm on the XL. Reach is moderate throughout, from 374 mm to 399 mm, which supports a more upright and less stretched riding position.
That adds up to a bike that should feel composed on rough pavement, dirt roads, and loaded utility rides, with less of the sharp, race-oriented feel seen on more aggressive gravel bikes. The 70-74 mm BB drop helps keep the rider centered in the bike for stability, while the steeper seat tube angles on smaller sizes, from 74.0 to 75.0 degrees, help maintain fit balance as the frame gets shorter. Overall, the Kanzo A’s fit and handling are geared toward comfort, confidence, and all-day usability rather than fast, twitchy responses.

The lineup.
5 builds.
The Kanzo A has been offered in a wide spread of builds that make sense for its role as an accessible, versatile gravel bike. The range includes a SRAM Rival 1x11 option as well as Shimano GRX builds in both GRX800 and GRX600 trims, with either 2x11 or 2x12 drivetrains depending on version. That gives buyers a meaningful choice between simpler 1x gearing for mixed-surface riding and commuting, or wider, closer-stepped 2x setups that better suit riders splitting time between road miles and gravel.
The GRX800 builds represent the higher-spec end of the lineup, while GRX600 versions are the more value-oriented choices without changing the underlying frame platform. The presence of both 11-speed and 12-speed GRX builds suggests Ridley has kept the model current through drivetrain updates while maintaining the same core chassis. Even without detailed component-by-component pricing here, the lineup clearly positions the Kanzo A as a frame platform that can be configured from practical entry-level gravel use up to a more refined all-road/gravel build.
