We have discussed this at least once before. I think the conclusion was that most of the shaping of metal tubes can be accomplished without hydroforming. I'm not saying hydroforming does not offer advantages, but rather that most of the features you see on the Breezer tubes can be incorporated without hydroforming. For example the tubes on my Merlin Works CR Ti frame are highly shaped but not hydroformed. Hydroformed aluminum tubes are considerably more modified beyond purely cylindrical than the Breezer tubes are. I wouldn't spend more for and get so excited by the descriptor, hydroformed, without some greater visual confirmation than I can see on the Breezer frame. Otherwise I would feel like I were succumbing to marketing fluff.

After all, it is not the hydroforming per se that makes a frame better, but the shapes it produces. If the shaping is minimal, so will be the effect, hydroformed or not. And don't forget that the same shapes can be produced by forging two pieces from sheet that are then welded together to make a tube. It isn't how you do it that matters, but what you do in the area of shaping.
