The HOOK takes it all

The HOOK takes it all- ticked off some Central Otago classics on my HOOK EXT-C like the Nevis, Thompsons Track and Omarama Saddle. Loaded it up for overnight trips in the Canterbury foot hills and rode fun flowy single track with chunky 2.2 MTB tyres.
Now running some semi slick 700c for faster road/gravel rides.
Super fun bike for going fast and far.

This bike is fast!

Time and again I’m surprised at the speed the Hook EXT-C carries. It’s supple enough for long days, and well thought out for bikepacking missions, but for me, most of all, I love that this bike is just pure flat out fun.
