Stay hydrated and save money when you bundle our water bottle and side-load bottle cage together! The Magnum Purist 21 oz. water bottle features FDA-approved food-safe materials free from BPA, a leak-proof cap, and a non-toxic ink design. It’s also made here in the USA (California, to be exact) and is 100% recyclable. Our Magnum Bottle Cage is ambidextrous, so you can load and remove your water bottle from the left or right side of the cage. The detachable arm lets you change sides whenever you want. Choose what works best for you! Please note: the Magnum Bottle Cage is not compatible with certain Magnum Bikes models. See Product Details for more info.
