Wanted to like this
March 8, 2015
I really wanted this rear hydration system to work! It's made for my bike. But, the cage is so tight that I can't pull the bottle out of it. The great thing is that the single arm is really aerodynamic and solid in place. If it weren't for the cage, I'd stick with this, but I ended up returning mine. For what it's supposed to do, somewhat pricey.
Merchant Response:
The cage that comes with this system is the Gorilla XT cage which has 14lbs of grip. This cage is used in order to prevent bottle launch on rough roads, unfortunately this benefit means that the bottles can be hard to pull out. We recommend changing to the standard Gorilla cage (7lb of force) if you are having issues pulling out your bottle during rides.
no bottles bouncing out; single arm that screws into seatpost on some TT bikes
pricey, too tight of a cage
