The well-known Tao is a classic bottle cage that has gained widespread praise. The Tao Carbon, which often is used in mountain stages where every gram counts, weighs no more than 29 grams and comes with a Source water bottle. The regular Tao is stamped from aluminium sheet, pressed into shape, anodized and partially coated in rubber. This is not just crucial to the design, it also provides extra grip. The weight is just 39 grams. The Tao Light is made out of plastic and weighs 32 grams.
