Lots on x-labs/seat mounted cages, but I’m looking for a carbon, frame mounted cage, that doesn’t launch my bottles and is reasonably priced. Any recommendations?
The new Zipp is sweet and better than the Profile Design. Zero Components makes a light one but I have no personal experience with it although we have sold a few.
I have the Zipp cages on my Merlin road bike and they really hold the bottles and I don’t worry about cracking one putting the bottle back 
(I use 21oz large screw-cap specialized bottles not the longer topped ones)
