I totally get where @

and still look good.
Butt rockets are all wrong. In the world of racing, design engineers go to great lengths to centralize mass for improved handling. The bottles should always be
within the frames. Neat, tidy, compact, precise, and balanced. Having those bottles up so high and aft ruins the CoG and destroys the handling of the machine. Additionally, they create significant drag and turbulence as air flows off the riders back and rumbles violently across the inefficiently angled bottles.
In short, they drain your energy, make you slow, and make the bike handle dangerously.
These are not random opinions. These are accurate findings from a study I conducted going up and down my driveway many times. Many. And my driveway is long. And sloped.
