2020 Bombtrack Hook EXT C

Bombtrack added the Hook EXT C model last year as its flagship carbon gravel bike. The bike is built for long haul bikepacking with plenty of frame bosses for fenders, racks, and other essentials. The 2020 Hook EXT C drops press-fit for a T47 bottom bracket and adds SRAM Rival and 650b Hunt Adventure Sport wheels with 2.0″ gumwall WTB Venture tires. The threaded T-47 bottom bracket is particularly welcome in a carbon frame given the eventual likelihood of a press-fit bbs creaking.
