Touring geometry

We've spent more than three decades perfecting the 520 geometry to suit the heavy loads and high miles of multi-day touring.

Mechanical disc brakes

Reliable stopping power in all conditions, including wet and muddy.

Puncture-resistant tires

Tough Bontrager Hard-Case tires help keep flats from slowing you down.

Tubeless Ready rims

Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road. No tubes mean there’s no pinch flats, allowing you to run lower tire pressure. With lower tire pressure you can increase traction, control. and comfort, reduce fatigue on you. Best of all, the tire sealant seals up punctures as soon as they happen!

Blendr stem

Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.
