I have figured out the primary build of my new bike, nice looking, light weight, SRAM Force, but I still need to find some bottle cages. Here is the catch, I do a ton of racing, that is what this bike is for, so I need something that will actually HOLD my bottles on rough roads at high speeds. For those who don't race, or don't race on some of the rough roads that I come across, imagine a hand full of water bottles flying back through the peloton, every race. The fact that these bottles could and do crash other cyclists is a concern, but more of a concern is the fact that you could go from 2 bottles to 1 with miles to go to the finish, this could literally be as significant to race results as a flat. IMO you could spend $100 on a cage that weighs nothing, but if it does not hold your bottle it is worthless. Currently I have had great luck with Bontrager's Race Lite Cage (never lost a bottle even on some of the most harsh roads), but they are so heavy and clunky looking it is hard to not want a nice light carbon cage on my new bike. However, I am NOT going to sacrifice function.
So I am looking for opinions of those who have raced on some of the worst roads and have had great success with a light weight (~25g), carbon cage.
