Since I started using the Gorilla Cage I haven't lost one bottle! Prior to that I had tried pretty much every rear mounted cage/carrier combination I could find in the market but was always loosing bottles. I've now used the Carbon Wing/Gorilla Cage combo on every training ride and race I've done in New Zealand including Ironman and numerous Half Ironman's without loosing one bottle!

The Xlab Gorilla Cage is the tightest tested rear cage on the market. Never loose a bottle from your saddle mounted carrier again. The Gorilla Cage was designed specifically for rear hydration systems with over twice the gripping force of conventional carbon cages with 6 high-shouldered carbon gripping fingers and tall retention tab at the top and thicker carbon. The Xlab Gorilla Carbon water bottle cage will fit on any standard cage mount.
