Rugged, 3mm Thick Butyl for a steadier ride

Thicker walls and premium butyl compound deliver enhanced damping, helping you feel more connected to the ground when navigating rutted lanes and uneven trails. The 3mm construction also supports better air retention, reducing the frequency of top-offs on long dirt-bike sessions.

• 3mm thick butyl rubber adds extra damping for a steadier ride on rough terrain.
• Improved air retention helps maintain consistent performance between inflations.

Riders who routinely push limits on gravel, roots, and dry dirt can appreciate the feel of a tube that stays steady under impact, contributing to a more confident ride experience.

Pinch- and Puncture-Resistant by Design

Designed to minimize pinch points and reduce the likelihood of pinch flats, these tubes are molded to resist twisting at the valve base. The robust construction helps stand up to the gravel and debris you encounter on off-road routes.

• Even molding around the valve stem base reduces twisting and pinch points on rough tracks.
• Puncture resistance is built into the thick walls to handle rocky surfaces and sharp debris.

For riders who frequently ride through challenging terrain, this design can contribute to fewer mid-ride interruptions and more time enjoying the ride.

TR4 Valve Stems for Easy Inflation and Safety

The short, straight TR4 stems are compatible with most hand pumps and provide straightforward inflation options. Secure vulcanization ensures the stems stay seated, helping you keep air where it matters most during a ride.

• TR4 valve stems are easy to inflate with common hand pumps.
• Stems are securely seated through a vulcanization process for dependable performance.

Having a reliable valve system can simplify maintenance and support a smoother tire setup, especially when you’re preparing for a day on the track or trail.

Designed for Off-Road and Dirt Bikes

These inner tubes are built with off-road and motocross tires in mind, tailored for 19-inch rims and 100/90-19 sizing. The combination aims to deliver a practical, cost-effective replacement option for riders who value durability on rugged surfaces and hard-packed tracks alike.

• Specifically engineered for off-road and motocross tires on 19-inch rims.
• Suitable for front or rear use on a range of dirt and dual-sport bikes.

Whether you’re tackling muddy trails or dry, rocky sections, this setup offers a straightforward path to maintaining ride quality and uptime during season-long adventures.
