Bontrager XR1 29er (29x1.9)

Designed in collaboration with Bontrager-sponsored pro race team riders, the XR1 is an ultra-fast rolling cross country race tire that's ideally suited for dry and dusty condition. Small, tightly spaced knobs provide plenty of fast-rolling traction, while siping (thin slits) across the middle knobs give even more grip on dusty surfaces. Designed for front or rear use.
