BOMBTRACK Hook EXT Ti Frameset - Titanium / Black

€3,450.00 (Save €52.00)
€3,398.00
Tax included

Premium technical gravel frameset, designed for riders who want the same use-case logic as the Hook EXT in a lighter, more refined, and more long-term oriented platform. The titanium frame and full carbon fork do not change its intended use—still focused on off-road adventure and bikepacking on rough terrain—but elevate overall build quality, structural comfort, and the level of custom build potential.

Bombtrack Hook EXT Ti Frameset

The Bombtrack Hook EXT Ti Frameset in Titanium / Black is the endpoint of the Hook platform: a 3Al-2.5V titanium frame paired with a dedicated Seido MGV full carbon fork, designed for aggressive gravel, technical riding and off-road bikepacking. Titanium offers outstanding fatigue and corrosion resistance and, together with the carbon fork, delivers a light, responsive and remarkably comfortable chassis for long days in the saddle. This frameset is meant to be the centrepiece of serious adventure builds.

What’s included in the frameset

Frame 3Al-2.5V titanium, thru-axle, rack / fender mounts, SRAM UDH derailleur hanger, compatible with multiple wheel sizes (27.5'' and 700C).
Fork Seido MGV full carbon, TA, 1.5" – 1 1/8" tapered steerer, fender / triple cage mounts, lowrider rack compatible, 180 mm max rotor size, internal hub dynamo cable routing.
Headset sealed external aheadset, 1.5" – 1 1/8".
Thru-axles 12 × 100 mm (front) / 12 × 142 mm (rear).
Seat clamp Bombtrack Prime 31.8 mm.

Use cases & configuration options

Technical gravel, singletrack & light MTB

Sharing the same intent as the steel Hook EXT but in a lighter titanium package, the Hook EXT Ti is built for demanding mixed terrain. With room for wide tyres, it’s well suited to rocky doubletrack, rooty singletrack and steep descents where many classic gravel bikes start to feel out of their depth. Independent reviews highlight how the EXT platform inspires confidence off-road and maintains composure even when the trail gets rough.

Off-road bikepacking & multi-day trips

Frame and fork are packed with mounts: triple cage on the fork, multiple bottle positions, rack and fender provision, and internal routing for dynamo lighting. Combined with the forgiving ride of titanium, this makes the Hook EXT Ti a highly capable choice for multi-day off-road trips and bikepacking routes where reliability, comfort and carrying capacity matter as much as speed.

One-bike solution for unknown routes

The Hook EXT Ti is often described as a “dream” adventure platform: 1x or 2x drivetrains, 27.5'' or 700C wheels and a wide range of setups are possible within the frame’s stated clearances. You can build it into a tough daily commuter, a long-distance gravel machine or a backcountry explorer, tuning wheels, tyres and gearing to your riding style while respecting the technical standards of the frameset.
