Twitch Ultra-Lightweight TPU tubes weigh 60–70% less than standard butyl tubes. Less weight at the wheel means faster acceleration and better performance—perfect for racers and serious BMXers. TPU's smooth surface reduces friction, so your bike rolls faster and more efficiently than with butyl tubes. This tube folds down to pocket size making it ideal as a spare tube to carry on the trail or track. The material also resists cuts and pinch flats better than standard tubes, and it stays stable in extreme heat or cold and won't degrade in sunlight, unlike latex tubes.
