Bidon

A water bottle gets used a hundred times per ride and never noticed. The BIXS bidon holds 500 milliliters, weighs 75 grams, and with a 74-millimeter diameter is matched to common bottle cages. The push-pull cap can be opened with your teeth, so you don’t have to take your hand off the handlebars. The plastic is dishwasher-safe, which makes the difference between a bottle you clean and one you eventually replace. At 200 millimeters tall, it also fits in smaller frames. A piece of kit you buy and then don’t mention again for years.
