Features

Named after a popular preserve in Colorado, Bontrager Betasso is an aggressive gravel tire made for maximum traction and durability in loose and rough conditions.

A durable 60TPI casing with squarewoven nylon sidewall and sub-tread puncture protection.

A firm and fast-rolling rubber at the center pairs with a medium-firm shoulder rubber for speed, cornering grip, and confidence.

Betasso RSL GX boasts a 350% improvement in tread puncture protection compared to the Bontrager GR2 Team Issue Tire it replaces.

A properly set up tubeless system lets you run lower tire pressure for better traction, added confidence, and a smoother, faster ride.

Bontrager offers a complete tubeless system including wheels, tires, sealant, valves, and rim strips. Every part of this setup is designed to work smoothly together, for the best in performance and ease of use.

If for any reason you're not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
