Bombtrack Hook
Bombtrack Hook
Description
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 tires on sealed hubs.
A Shimano GRX groupset with a subcompact 46 / 30T crankset, combined with an 11 – 36 T 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.
