Bombtrack Hook Frameset

The Bombtrack Hook Frameset in Metallic Red is a steel gravel / all-road frameset built from Columbus Cromor tubing with a full-carbon fork, designed for riders who want a fast, versatile bike for compact gravel, white roads and rough tarmac. Thru-axles, a T47 bottom bracket and multiple mounting points make it a solid platform for performance-oriented builds that still keep everyday practicality in mind.

  • Fork: full carbon with thru-axle, tapered 1.5"–1 1/8", triple cage mounts that can also be used as fender mounts, plus internal routing for a hub dynamo cable.
  • Headset: sealed external headset, 1.5"–1 1/8".
  • Thru-axles: front 12 × 100 mm, rear 12 × 142 mm (included).
  • Seatpost clamp: Bombtrack Prime 29.8 mm (included).

Intended use & possible builds

Fast gravel & all-road

Built around a lightweight steel frame and a full-carbon fork, the Hook is made for fast gravel riding: tyre clearance up to 700C × 42 mm allows efficient setups with enough grip and comfort for compact gravel and white roads.

Sport commuting & light bikepacking

With mounts for fenders, racks and triple cages on the fork, the frameset suits daily commuting or light bikepacking builds: 1x for simplicity, or 2x for riders who prefer tighter gear steps, with a broad choice of front chainrings within the frame’s stated limits.

Year-round mixed use

The combination of steel and carbon, together with flat-mount disc brakes, makes the Hook suitable for hard use in variable weather conditions. You can steer the build towards comfort or responsiveness by choosing tyres, wheels and drivetrain options within the standards supported by the frameset.

Frequently asked questions about the Bombtrack Hook Frameset

Is the Bombtrack Hook Frameset a gravel frame or an all-road frame?

The Bombtrack Hook Frameset is designed as a fast gravel platform with a strong all-road character. It is intended for compact gravel, white roads and rough tarmac, with a sportier and more responsive ride than a frame focused more heavily on pure commuting use.

What is the difference between the Bombtrack Hook Frameset and the Arise Frameset?

The Hook is more clearly aimed at fast gravel riding and sporty handling, thanks to its full-carbon fork, T47 bottom bracket and more explicitly performance-oriented platform. The Arise, by contrast, is more versatile and utilitarian, also well suited to commuting and light touring builds.

What tyres can the Bombtrack Hook Frameset take?

The fork accepts up to 650B × 52C or 700C × 45C without fenders. The frame itself is rated for XS–S with 650B × 42C and M–XL with 700C × 42C without fenders.

Is the Bombtrack Hook Frameset compatible with both 700C and 650B?

Yes, but it needs to be understood correctly. The fork has broader compatibility, up to 650B × 52C or 700C × 45C. The frame, however, is size-specific: XS–S are intended for 650B × 42C, while M–XL are intended for 700C × 42C. So this does not mean identical dual-wheel compatibility across all sizes.

Can you fit fenders and racks to the Bombtrack Hook Frameset?

Yes. The frame has mounts for fenders and racks, while the full-carbon fork includes triple cage mounts that can also be used as fender mounts. This allows for sporty commuting or light bikepacking builds.

Is the Bombtrack Hook Frameset compatible with both 1x and 2x drivetrains?

Yes. It supports a 1x chainring up to 40 teeth with a 45 mm chainline, or a 2x setup up to 48 / 32 teeth with a 46.9 mm chainline.

Is the Bombtrack Hook Frameset suitable for light bikepacking?

Yes. The mounts on frame and fork make it suitable for a light bikepacking build, provided the project stays consistent with its nature as a fast gravel frame rather than a heavy touring platform.

What technical standards does the Bombtrack Hook Frameset use?

It uses an 86.5 mm T47 bottom bracket, 12 × 100 mm and 12 × 142 mm thru-axles, flat-mount brakes and a 27.2 mm seatpost. These are modern standards and highly relevant for anyone planning a build from scratch.
