Let's ride! Keep hydration within an arm's reach with this sturdy plastic bottle cage from Crown Sporting Goods. Boasting an efficient, no-frills design that includes a mounting plate with a lot of wiggle room to accommodate different threading patterns, these bottle cages are simple. And thanks to their hardy plastic construction, they're strong too. Their firm plastic arms wrap tightly around the frame of your bike for a snug and sturdy fit. Not much more you can ask from a cup holder. Why you'll love it: Though our water bottle cage is engineered to fit all sorts of water bottles, your best fit out of the box will be a 3" diameter bottle. However, due to the flexible plastic material, these bottle cages can stretch to tightly fit just about any shape or size of water bottle. Once you're fitted, installation is quick and easy, whether on your handlebars or on your frame, with just a few screws, you are ready to ride. *Hardware and fasteners not included.*
