Grifn Road Shimano GRX DI2 - 2x12

Ridley offers the Grifn across a wide spectrum of builds, heavily utilizing Shimano and SRAM groupsets. The lineup splits into road-focused configurations with compact double chainrings and gravel-oriented setups featuring wider gear ranges and 1x options. Entry points typically feature mechanical Shimano 105 or GRX, while premium tiers move to electronic shifting like Shimano Di2 or SRAM AXS.

The frame utilizes a BB86 press-fit bottom bracket, a standard 27.2mm round seatpost, and a Universal Derailleur Hanger (UDH), which simplifies sourcing replacement parts and ensures compatibility with modern drivetrains. Most pre-configured models roll on DT Swiss G1800 alloy wheels wrapped in 32mm road tires or 35mm to 38mm gravel treads.

While the carbon frame itself is praised for its high quality and sub-kilo weight, some reviewers noted that the stock alloy wheels on mid-tier builds feel slightly heavy relative to the chassis. Because Ridley offers an extensive online configurator, buyers can easily upgrade wheelsets or swap drivetrain components at the point of purchase, allowing the bike to be tailored precisely to a rider's local terrain and budget.

Reviewers consistently characterize the Grifn as a highly capable multi-surface machine, though they emphasize that tire selection ultimately dictates its personality. On tarmac, the bike accelerates efficiently and maintains speed well, with a ride quality that effectively dampens road chatter. Testers praised its high-speed stability, noting that it "runs very smoothly and does not steer too hectically" (Unicorncycling) on descents.

Transitioning to unpaved surfaces, the Grifn handles hardpack and smooth dirt with a sporty, engaging demeanor. However, its road-oriented roots become apparent on rougher trails. The geometry requires active rider input off-road, as the "slightly steep head angle" demands concentration on "trickier and twitchier surfaces" (Velo). Low-speed handling also drew specific observations, with one tester noting that "in slow, tight turns or when hitting the brakes in a bend, the Grifn tends to break away" (Granfondo).

The consensus points to a highly successful compromise for mixed-surface riding. While it lacks the explosive snap of a dedicated road racer and the rugged composure of an adventure gravel bike, it delivers a refined, comfortable ride. Testers frequently recommended owning two wheelsets to fully exploit the frame's broad capabilities without being held back by compromise tires.
