BOARDMAN bottlecage, £35,

There’s not too much you can say about waterbottle holders — you simply want them to grip your drinks bottle when the going gets bumpy and not weigh too much. With a full carbon-fibre construction and supplied with two titanium bolts, this Boardman cage fulfils both ideals. It weighs just 28g and fits most regular bottle sizes, though its price only makes sense if you’re a serious sportive rider. JK

PROS: Strong, lightweight
CONS: Hefty pricetag
