Description Ideal for both road and path riding where repeated bottle jarring isn't a concern, Bontrager's 5mm cage is constructed from lightweight 6061-T6 aluminum that's topped with a durable powder coat finish.
Recommendation: This bottle cage not only holds regular cycling water bottles, but also holds disposable bottles with a little bend of the cage. When I worked for the bike shop, we sold about 100 of these a week because they just worked. It is that simple. Oh, did I mention they are cheap?
Pros: Light, inexpensive, holds soft plastic bottles very well.
Cons: Won't hold anything other than "traditional" bottles
Recommendation: Bought on clearance at LBS, didn't really need a cage but figured what the hell. Like has been said, really holds soft plastic bottles well, Nalgenes and the like not so much. Still, usually only wanted to hold the plastic bottles anyway!
