Get a flat but finish the race without stopping? Yeah, that used to be a badge of pride for cyclocross racers, now its something anyone can do on their road bike.Vittorias original Air-Liner Light Road added their same run flat technology to tire inserts for skinny tires, and now it gets an upgrade that makes it easier to install and have less impact on your sealant.But first, heres why you should care about these inserts at all: It uses a semi-closed cell foam that works by slowly absorbing the air pressure in fully inflated tires. Then, when you puncture, the rapid release of air from your tire causes them to swell up and fill the tire, keeping you riding on airalmost like normal.Weve tested them on the trails, and the tech works. But theres more to it. Not only does it work to keep you rolling when you flat, it changes the ride quality for the better.The Air-Liner Light inserts let you run slightly lower pressure for better traction and a smoother ride. This works because theres a foam insert to mitigate the hits and provide support in the corners.Now, the new Air-Liner Light Road uses a better material and extrusion process, making it easier to slide into the tire during installation. That materials surface is also less likely to hold sealant, meaning you can use slightly less (they still recommend at least 10ml per tire).All photos courtesy of Vittoria.Combined, the sealant plus insert lets you ride up to 50km (~30 miles) after a puncture. The insert gradually releases its air, so you wont get that dangerous blowout, and even when its flat, its still equivalent to roughly 1 bar (14.5psi) of air pressure. Its enough to get you homeor across the finish line.They add just 30-40g per tire (depending on size), which isnt enough to stop EF-Education First riders from using it. MSRP is $77.99 per wheel.Vittoria.comThe post Vittoria Air-Liner Light Road Gives You 50km of Run Flat Protection appeared first on Bikerumor.
