Overview
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. 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.
