Bottles with shorter groves that do not fit properly into the hook like the Camelback Podium, and bottles with grooves that are not uniform around the entire circumference like the Polar Insulated bottles are not recommended for use with the XLAB GORILLA Cage, In our experience these two bottles do not stay in place on rear carriers due to the lack of a groove for the cages to grip.Buy XLab Accessories from Chain Reaction Cycles, the World's Largest Online Bike Store.
