It's easy to rip a bite valve when removing if from the hose, especially if you clean your reservoir after every ride. Standard spares are £5.99 each, but you can buy a selcetion pack of three candy colours for £15. They're no different performance-wise, but they do add a splash of colour and buying in bulk means they're £3 cheaper.
