Hook
"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."
Naturally, our steel Hook is something special, being built from double-butted Columbus Cromor tubing, with a tapered headtube and a T47 bottom bracket. XS and S sizes feature 650B wheels, M - XL have 700C options and both run WTB tubeless rims and tyres on sealed hubs. A Shimano GRX groupset with a subcompact 46 / 30T crankset, combined with an 11 - 36T cassette helps to keep you spinning up and over the hills, and GRX 400 callipers deliver powerful braking on the descents. The frameset is bedecked with mounts for every scenario, including a top tube bag, triple cage mounts and bottle mount options, as well as internal dynamo routing on the full carbon fork.
