Experience unparalleled protection and performance with the Vittoria Air-Liner Tyre Insert Protect Downhill. Designed specifically for downhill enthusiasts, this innovative insert is crafted from high-density polymer foam that offers exceptional durability and resilience against harsh trail conditions. Its revolutionary "T" shape design not only enhances shock absorption but also significantly improves tyre stability and bead retention, ensuring your tyres stay securely in place even during the most aggressive descents.
The Air-Liner Protect Downhill version is engineered with a higher density foam to resist the intense impacts and forces encountered during high-speed downhill rides. This robust insert acts as a solid barrier between your rim and tyre, effectively preventing punctures, sidewall damage, and pinch flats without compromising rolling resistance. Compatible exclusively with tubeless setups and multiway tubeless valves, it provides a seamless fit and easy installation, eliminating the need for cutting or zipping thanks to its complete loop design.
Available in sizes 27.5" and 29", and suitable for tyre widths between 2.4" and 2.6" with rim widths from 25mm to 35mm, the Vittoria Air-Liner Protect Downhill insert is a must-have for riders seeking confidence and control on the most demanding downhill trails. Lightweight at just 175g, it enhances your ride without adding unnecessary bulk, making it ideal not only for traditional downhill bikes but also for e-bikes that require durable and reliable tyre protection.

Can I use the Air-Liner Protect Downhill insert on an e-bike?
