it sucks. your experience may differ, but I certainly would not recommend. too many launched bottles, regardless of carrier - tried Elite, Tacx and Profile cages.
Well now, I didn’t say I don’t launch bottles with the setup. Let’s just say the Profile Designs cages aren’t particularly good for the Saddlewing.
Aside from bottle launching (which I think can be satisfactorily reduced with the proper cages), what sucks about it is that it sits way up high, especially if you use taller water bottles. Not conducive to “aeroness” and it can be annoying when you sit up and it digs into your back. I think I may try the Flatwing.
