From Bontrager : For the new XR3, we wanted something that was light and fast enough to be a legitimate cross country race tire, but still have durability and traction for confident cornering on technical trails. The new XR3 is a race-ready XC tire that is also ready to rip.
To do this we paired the smooth, fast rolling centre tread of the beloved XR2 with the more aggressive, confidence inspiring side knobs of the XR4, creating a tire that is as versatile as it is fast. The new XR3 brings the weight and speed of a race tire with the versatility to bite into a corner and provide confident traction in rougher terrain. Perfect for the customer that wants a single tire that is up for anything.
Like all XR Series Team Issue tires, the XR3 features a lightweight Inner Strength casing for additional sidewall reinforcement and is designed to be Tubeless Ready for easy setup and lasting tubeless performance with Bontrager TLR wheels and sealant.
