The 2017 Bontrager XR4 Team Issue TLR is a high-end cross-country off-road tire. Tubeless-ready and lightweight, the XR4 includes Trek's Inner Strength casing to provide a surprisingly tough sidewall in a racing tire. The tread is aggressive, optimized for loose dirt and rock, with outer blocks providing impressive hookup on steep, off-camber pitches. Racers will appreciate the low rolling resistance of the centerline. Offered in all three standard diameters, with multiple widths available for 26" and 27.5".
A good cross-country racing tire.
