Ridley Grifn A GRX600 gravel bike Chain Silver Gray/Black

Description

Ridley Grifn A GRX600 gravel bike Chain Silver Gray/Black is an aluminum gravel bike for all-road riding, fast gravel, and bikepacking with a gear rack. In concept, it targets the mid-range segment, where functional component spec, tire clearance, and the frame’s mounting readiness are key. The build combines an aluminum frame with a gravel fork and a Shimano GRX groupset for a wide gear range.

Frame and geometry

The foundation is the Grifn A frame made from an aluminum alloy with a 12×142 mm rear thru-axle. The frame uses a UDH hanger and features internal cable routing, including provision for internal dynamo wiring. Multiple mounting points and fender mounts are included, expanding its use for commuting and longer trips. The geometry matches the all-road concept of the Grifn model range and is available in sizes XS, S, M, L, and XL.

Components

Drivetrain: Shimano GRX600 shifting runs in a 2×12 configuration. 46–30 crankset and a Shimano 105 11–36 cassette are complemented by a Shimano GRX 800 front derailleur and rear derailleur.

Brakes: Shimano disc brakes in a gravel-specific setup are used. Control is integrated into the Shimano GRX600 shift levers.

Wheels and tires: Shimano RS171 DB wheelset is ready for 700C tires. Vittoria Terreno Dry 700×38c tires match the frame’s maximum clearance of 38 mm.

Cockpit: 4ZA Stratos Gravel handlebars are selected by size in widths from 420 to 480 mm. The Forza Stratos stem is 100 mm long, and the Forza Stratos seatpost has a 27.2 mm diameter.

Ride characteristics

The aluminum frame with thru-axles is built around precise tracking under braking and through gravel corners. The 46–30 double chainring maintains tight gearing for road pace while still offering low gears for longer climbs. 700×38 c tires increase stability on rough surfaces and keep rolling resistance on paved roads within reasonable limits. Mounting points and fender mounts broaden usability for year-round riding, even with bags.

Who it’s for

The bike is intended for experienced riders who want one bike for asphalt, gravel, and lighter off-road terrain without switching to a mountain bike. It’s well suited to gravel rides, fast transfers between segments, and bikepacking, where tire clearance and accessory readiness matter. Compared to purely race-focused gravel bikes, it places greater emphasis on frame practicality and mounting compatibility.
