It features a center section that offers excellent pedaling and braking traction, and is built upon a supple 260tpi handmade casing. There's also an anti-puncture strip under the tread and reinforced polyester in the sidewalls for extra durability.

This is a tubular tire (also called a "sew-up"). It is compatible with tubular rims and is installed with glue or a special adhesive tape. It will not work on standard clincher rims. If you have any questions about compatibility or mounting, please contact us for details.
The high-count thread-per-inch casing makes this tire conform to the trail for superior cornering and a smoother ride.
