Bottle cages are good because they provide a form of storage for your refreshments to ensure you stay hydrated. You can ride your bike and grab your bottle from the cage without experiencing any negative impact to your ride.
Bottle cages come in a variety of sizes to suit your riding needs. They come in sizes from 500ml up to 1,000ml, making it possible to carry 2,000ml of fluid on your bike. Bottle cages have also received the lightweight treatment with materials such as aluminium, steel, titanium, plastic and carbon fibre being used.
