BOMBTRACK Hook Frameset - Metallic Teal / Black Fade

The Bombtrack Hook Frameset in Metallic Teal / Black Fade is a gravel / all-road platform built from Columbus Cromor double-butted steel and a full carbon fork. Thru-axles, a T47 bottom bracket shell and generous mounting options for racks, fenders and luggage make it a strong foundation for fast mixed-surface builds with a distinctive look.

Use cases & configuration options

Fast gravel & all-road

With a lightweight steel frame and full carbon fork, the Hook is ideal for fast gravel and unpaved roads. Tyre clearance up to 700C × 42 mm (or 650B × 52 mm) gives you room to choose between faster rolling tyres or more aggressive tread patterns while keeping a balanced mix of comfort, grip and efficiency.

Sporty commuting & light bikepacking

Multiple mounts for racks, fenders, a top tube bag and triple cage mounts on the fork make the frameset suitable for year-round commuting or light bikepacking setups. Both 1x and 2x drivetrains are possible within the specified chainring clearances, so you can prioritise simplicity or tighter gear steps.

One-bike mixed-use projects

The Hook works well as a “one-bike” frameset for riders who want a single machine for gravel, all-road riding, day trips and everyday use. By fine-tuning wheels, tyres and drivetrain, you can steer the build towards comfort, responsiveness or a balanced all-round character, while staying within the frame’s technical standards.
