Bontrager XR1 MTB Tire

The XR1 is specifically optimized for firm, fast-rolling trail conditions. While it offers predictable grip, it is not designed for deep mud or loose, technical terrain where a more aggressive, knobby tread pattern would be required.

The 60a durometer indicates a medium-firm rubber compound. This provides a balanced mix of durability and grip, ensuring the tire lasts longer while still offering enough traction to help young riders feel confident in corners.

No, this is a wire-bead clincher tire designed for use with an inner tube. It is not compatible with tubeless setups.

This tire fits standard 12-inch wheels with an ETRTO size of 57-203. Before purchasing, verify that your child's bike frame has enough clearance for the 2.25-inch width, as some smaller frames may be designed for narrower tires.

At 615 grams, this tire is designed to be lightweight to reduce rotational mass. This makes it easier for children to accelerate, maintain momentum on flats, and climb hills without feeling weighed down by heavy equipment.
