The difference between latex tubes and the far more common butyl tubes is more than price. Latex tubes are thinner and lighter and more supple but lose pressure far faster and most users pump them up before every ride, even if its the next day. Butyl is cheaper and usually heavier but tougher and retains air pressure far better.
