XLAB Chimp Cage
The cage is light, strong, and has a strong grip. Make sure to use the screws and washers provided to ensure proper installation. There are some issues with too much grip during insertion and removal and especially after 3 hours riding (i.e. bottle rotation from the back). This could be caused by bottles expanding and the cages expecting a true fit. The strong grip may also leave marks on bottles and have paint, from the bottles, sticking to the cages.
