Bombtrack Hook EXT review

Oct 2021

With a large tyre clearance and plenty of mounts, the Bombtrack Hook EXT is a hugely versatile machine. It manages to offer an impressively fun and nimble approach to the tracks and trails regardless of whether you are riding it loaded up for an adventure or smashing it around stripped back. It’s like a cyclocross bike on steroids! Range overview: Bombtrack Bicycle Co.

Bombtrack Hook 2 in bikepacking review

Oct 2020 · Benjamin Topf

Hardly any other German brand has made such a name for itself in the international bikepacking scene as Bombtrack. The Hook 2 combines features from numerous disciplines, including a big portion of bikepacking DNA. Is that enough to hold its own against the competition?
