Description
We say…
The Bombtrack Hook Ext is arguably one of our favourite bikes in the shop. It can carry out every type of gravel riding and even opens up as the ultimate bike packing rig. Proven on the Highland 550, this Bombtrack is bombproof and super fast, it’s handling is something that needs to be ridden to be believed…
They say…
Smaller wheels, bigger tyres, rowdier personality. The burly Hook EXT is made for the most extreme drop bar adventures. A classic case of “if it ain’t broke – don’t fix it!”. Besides adding a wider, more durable T47 bottom bracket we’ve revised the cable routing to keep the bike looking clean with any combination of derailleurs and dropper posts. Besides this, the bike retains the same gorgeous matt metallic grey paint scheme and awesome parts list that’s made it a pin-up for many gravel nerds.
