Bombtrack Hook - glossy red

Of course, our steel hook is something special, as it is made from double butted Columbus Cromor tubing, a conical head tube, and a T47 bottom bracket. Sizes XS and S come with 650B wheels, M–XL with 700C options, and both are equipped with tubeless WTB rims and tyres on sealed hubs. A Shimano GRX groupset with a compact 46/30T crankset combined with an 11–36T cassette ensures you can ride uphill and over the hills, and GRX 400 brake calipers provide powerful braking on descents. The frame set is equipped with mounts for every scenario, including a top tube bag, triple cage mounts, and bottle cage options, as well as internal dynamo cable routing on the full carbon fork.
