Hook AL
"load up and head off"
Bombtrack Hook AL Frameset
The Hook AL is a lightweight aluminium gravel frame built around a T47 bottom bracket and a full carbon fork with triple cage mounts. An ovalized toptube, low seatstays, and oversized downtube balance comfort, power transfer, and steering precision, while direct toptube bag mounts, additional bottle mounts, and front derailleur compatibility add practicality. Completing this versatile package is a dose of futureproofing that comes with the UDH derailleur hanger.
