The Bontrager Betasso RSL GX TLR Gravel Tire is a true conqueror of rugged terrain. Inspired by the challenging trails of Colorado, these tires offer ultra-aggressive performance, delivering exceptional grip and durability in mixed and loose conditions.

Constructed with RSL GX technology, these tires feature a robust 60TPI casing, fortified with bead-to-bead and sub-tread puncture protection. The Gravel Dual-Compound design incorporates a firm center for maintaining straight-line speed, complemented by medium-density shoulder knobs that provide reliable traction during cornering.

Designed for the most demanding gravel adventures, the Betasso tire boasts an aggressive tread pattern that excels in mixed and loose conditions, ensuring superior grip and durability. Product details include RSL GX Construction for enhanced strength and puncture resistance, Gravel Dual-Compound for optimal performance, and Tubeless Ready (TLR) compatibility for easy setup and added puncture protection.
