Ultralight tubeless insert for road speed
Air-Liner Light Road is an ultralight tubeless insert developed to maximise road racing performance. Proven at World Tour level: it improves bead stability, supports run-flat riding and protects against impacts while keeping the tyre feeling fast and supple.
The ultralight material adds just 29–40g per wheel depending on size. Its volume is optimised for modern wide rims and tyres; if you puncture, the insert lets you ride on for up to 50 km.
For:

More grip and comfort without worrying about rim strikes.
The foam expands when you puncture; the TLR bead stays secure.
More sidewall support — faster, more confident cornering.
Almost no effect on rolling resistance.
Adds just 29–40g per wheel, maximising speed on race days.
