The Widefoot LiterCage™ allows you to carry your favorite bottles on your bike. Compatible with a variety of 3.5? (89mm) diameter water bottles including those made by Nalgene and other top brands. Our unique 7-slot mounting bracket allows attachment at multiple positions on frames and forks with two-bolt, or three-bolt mounting systems. Full stainless steel construction provides durability, corrosion-resistance, and a secure hold. Choose from two finishes: Polished or Black. As with any type of coating, our Black option will show some wear over time in locations where bottles contact the cage.
