Betasso RSL GX
Named after a popular nature preserve in Colorado, the aggressive Bontrager Betasso gravel tire is designed for maximum traction and durability on unpaved surfaces and in challenging conditions.

RSL GX construction
60 TPI density base layer with square woven nylon sidewall and under-pattern puncture protection.

Two-component compound for gravel
The middle is a firm, fast-rolling rubber, while the rubber on the shoulders is medium hardness. The result is a tire that offers speed, cornering grip and confidence.

A 350% improvement
The Betasso RSL GX boasts 350% better puncture protection compared to the Bontrager GR2 Team Issue tire it replaces.

Choose Tubeless
With a properly set up tubeless system, tires can be under-inflated for better traction, more confidence and a smoother, faster ride.

Ideal Interplay
Bontrager offers a complete tubeless system including wheels, tires, gaskets, valves and rim bands. The individual components of this kit form a perfect unit that ensures superior performance and ease of use.

Recommended Gravel Tire Pressure
Find out the weight of your rider and compare it to the width of your tires to find the recommended pressure. It is advisable to under-inflate the front tyre slightly. If you find your tyres too soft or too hard, increase or decrease the pressure to match the surface you intend to ride on. The recommended pressures are for guidance only. Do not exceed the maximum pressure rating on the sidewall or rim. Follow the rim manufacturer's recommended pressure ranges for the rim and tire width combination.

Sealant Recommendations by Tire Size
When installing tubeless tires, follow the sealant recommendations for your tire size.
