Letting you keep the tempo high on gravel or unpaved roads.

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 cyclocross bike."

Introducing the Hook

A capable steel frame, light carbon fork, and mid-width 700C tyres render the Hook fast and versatile. Fitted with Shimano’s latest GRX groupset, a double crankset provides close-ratios but a wide range. Letting you keep the tempo high on gravel or unpaved roads, it can be loaded up in an infinite number of ways. Dotted with fixing points, including direct mounts for a top tube bag, triple cage mounts, plus rack and fender mounts, it’s happy to carry whatever you need. Alternatively, leave it stripped-back and free to fly. New for 2021, size-matched 650B or 700C wheels now standardise the bike’s geometry across all sizes.

 

  • * Size XS and S will come with 650B wheels to ensure proper fit without any compromises in geometry.
  • * Columbus Cromor double butted frame with 86.5 mm wide T47 bottom bracket to increase tire clearance.
  • * Full carbon tapered fork with triple cage mounts.
  • * Hydraulic Shimano GRX 400 2 x10 groupset.
  • * KMC X10 EPT Anti Rust Chain.
  • * Bombtrack Tau 12 mm through axle hubs.
  • * Toptube bag direct mounts, triple cage mount ondown tube and seattube for optimized bottle position, bottle cage mounts underneath the downtube and rear rack mounts.

    * Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
