Ridley
Grifn A RoadShimano 105 - 2x12
The Ridley Grifn A Road is the aluminum entry point into Ridley’s broader Grifn all-road platform, introduced in 2024 to deliver the same mixed-surface concept at a lower cost than the carbon Grifn models. It uses a 6061-T6 triple-butted aluminum frame paired with a full-carbon fork and carbon steerer, which sets the tone for the bike’s purpose: practical, modern, and versatile rather than narrowly focused on pure road racing. This is a bike intended to cover fast paved riding, rough roads, and light gravel duties without requiring a separate dedicated machine.
What distinguishes this generation is how closely it mirrors the feature set of the carbon Grifn family. The frame incorporates UDH compatibility, semi-integrated cockpit cable routing, and internal routing provisions for dynamo and rear-light wiring, all of which point to a forward-looking and utility-conscious design. Tire clearance is a central part of the package, with room for up to 38 mm tires in general use and up to 40 mm with a 1x drivetrain, reinforcing its place in the growing all-road category. Shared geometry with the other Grifn models further positions it between conventional endurance-road handling and light gravel stability, making it a clear fit for riders who want one bike to span road riding and mixed terrain.

Geometry & fit.
7 sizes published.
The Grifn A Road’s geometry sits squarely in modern all-road territory, using stable, moderate numbers rather than aggressive race-bike figures. Across most sizes, the head tube angle is 72°, relaxing slightly to 71.5° on XXS and XS, which should produce calmer steering than a typical road race bike, especially on rough surfaces or with larger tires. Chainstays are a consistent 420 mm in every size, and wheelbase ranges from 982 mm in XXS to 1057 mm in XL, both of which support predictable handling and better composure on mixed terrain. BB drop is also fairly generous at 73 mm in S and M, 71 mm in L and XL, and 75 mm in the two smallest sizes, helping keep the rider centered in the bike rather than perched on top of it.
Fit trends are similarly balanced. Reach numbers run from 372 mm in XXS to 414 mm in XL, while stack spans 515 mm to 622 mm, indicating a more upright and accessible position than a low-slung race frame. The effective top tube grows from 515 mm in XXS to 605 mm in XL, and seat tube angle tapers from 74.5° in the smallest sizes to 73.5° in XL, a typical approach to keeping rider weight distribution consistent across the range. Overall, the geometry suggests a bike built for long rides, varied surfaces, and stable descending rather than sharp, criterium-style handling.

The lineup.
1 build.
Ridley lists the Grifn A Road in a Shimano 105 2x12 build, keeping the lineup straightforward and aligned with the bike’s do-it-all brief. That choice makes sense for an all-road aluminum platform: 105 12-speed offers modern gearing, broad parts compatibility, and a level of performance that is well suited to riders who want reliable road manners without moving into premium-price territory.
With only one listed build, the emphasis is less on choosing between spec tiers and more on the frame platform itself. The key story is that Ridley has paired a lower-cost aluminum chassis with contemporary standards such as a full-carbon fork, semi-integrated routing, and UDH compatibility, rather than treating this as a stripped-down budget model. For buyers considering the Grifn concept but not needing a carbon frame, that makes the Grifn A Road the pragmatic option in the range.
