Technical interpretation

The Hook EXT Ti offers generous tyre versatility, with different limits at the frame and fork:

• In 650B format, the frame takes up to 52 mm while the fork accepts up to 57 mm, allowing high-volume setups for comfort and off-road control.
• In 700C format, the fork allows up to 57 mm, while the frame is limited to 40 mm — this rear limit defines the real maximum in 700C mode.

This opens the door to effective configurations:

• Wider front tyre for traction and steering confidence (front traction bias).
• Narrower rear tyre for efficiency and speed.
• Balanced setups for gravel touring or rugged exploration.

This flexibility is one of the reasons the EXT Ti is so well-suited to long-distance adventure riding.

¹ The bike size recommendation is intended as an approximate guideline to narrow down options based on rider height. Proper bike fitting is complex and also depends on other body measurements and factors. Since no two riders are exactly the same, these recommendations cannot be 100% accurate for everyone. The best way to determine your ideal size is to contact your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter.
