One of my Zipp carbon cage has broken this summer (the lower carbon part which stabilize the bottom of the bottle) and I had to glub some aluminium part I had at home to give some stability but I lost all benefit of the low weight purpose of these bottle holders.

Now i'm building a bike for my girlfriend and I will prbably trsnfer my old Zipp cages to her bike and will buy some new ones for my road bike.

What would you go for, in your opinion, what is the best weight/price/quality (holding the bottle firmly) carbon cage in the market these days?
