Every knows how important weight is when setting up a race bike-the lighter you bike the faster you go. However, some weight saves more than others. Rotating weight multiplies the actual weight being pushed around the track....that's why when you spin a wheel in your hands it feels heavier than it does when not spinning. These race lite tubes from Intense save over an ounce (25g over standard innertubes) and are the cheapest way of saving weight on your bike. After spending a small fortune on a light setup, can you afford not to have these?
