The foam tyre inserts from Flat Tire Defender are all the rage. They offer increased security while slamming down the trail with a tubeless setup. They help protect your rim, minimize tyre burping, provide a progressive wheel dampening over rocks & roots and minimize tyre sidewall roll. All this works together turning your tyres into a 3rd set of suspension. An added plus is the ability to ride lower pressures than ever before on the most extreme trails. With all that Flat Tier Defender has to offer, it’s no wonder they are ridden by Downhill pros.
