Bombtrack Hook - glossy red

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