well the belt teeth may have a different diameter effect, so it's not to say that it's akin to having a 55t 22t 1/2 chain drivetrain, but the ratio would be the same, yes.
and considering how ****ing expensive and impractical that thing is... it's still otherworldly awesome.
i mean dear GOD. in a perfect world, you'd ride downhill through a crisp breeze on a sunny day at a fun spin and a fast-enough-to-still-enjoy-it pace, and this is the bike you'd be on.
