The XLAB Gorilla Bottle Cage keeps a firm grip on bottles over rough roads to keep them from ejecting, especially when used on rear saddle mounts like those used on triathlon bikes. Its holding power comes from six high-shouldered arms, a tall retention tab, and stiff carbon construction. Delivering 2X the security of conventional cages, it's still easy to insert and remove bottles thanks to its flared entry.

Claimed weight is 39 g. Requires traditional bottle shapes with a deep, uniform groove near the top to clear the retention tab. Bottles such as the Camelbak Podium are not compatible.
