Materials & Construction
The Overton features a durable tubeless-ready casing constructed with a high-volume, lightweight rubber compound designed for reliability and comfort. The tire incorporates EPS (Exceptional Puncture Safety) technology-a proprietary layer of rubberized poly-fiber material nestled between the tread and casing-providing superior puncture resistance and enhanced safety on mixed terrains.
Performance & Engineering
Designed for speed and efficiency, the Overton's semi-slick profile with a smooth, siped centerline minimizes rolling resistance, allowing for faster straight-line rolling on gravel and pavement.

Components & Technology
Equipped with DC (Dual Compound) technology, the Overton optimizes traction and efficiency by employing a lower rolling resistance compound at the center, complemented by a tacky, high-grip compound on the shoulders for superior cornering performance. The TR (Tubeless Ready) casing simplifies setup-just add sealant and inflate for a secure, puncture-proof ride that minimizes maintenance and downtime.

Its versatile 700x40 size makes it perfect for gravel adventures, bikepacking, and light touring, offering a comfortable, stable ride across mixed surfaces.
