The Hook might have been designed as a gravel racer, but that doesn’t stop it also being a perfect tourer, commuter, or even summer-season cross bike.


Which to choose: speed or storage space? You can have both with a Hook. With an able steel frame and carbon fork, this bike is fast and versatile. Size-matched 650B or 700C wheels across the sizes provide control and comfort, while the Shimano GRX groupset and double crankset give you a close ratio with a broad range of gears.

Take your pick from a range of fixing points, including a direct mount for a top tube bag, triple cage mounts, rear rack and fender. Or, leave it stripped back and fly.


Crafted from Columbus Cromor double butted steel, the frame features a through-axle dropout, practical rack and fender mounts, and an 86.5 mm T47 bottom bracket shell for robust support.

The Seido RGT fork, made from full carbon, accommodates a through-axle, offers mounts for fenders and triple cages, supports up to a 180 mm rotor, and includes internal routing for a hub dynamo.

Gear changes are smooth and precise with Shimano GRX ST-RX400 STI hydraulic levers, designed for a 2 x 10 drivetrain, blending performance with reliability.
