On paper it may claim a such things as nimbler handling, better power transfer (less rear triangle flex since everything isnt quite as long back there), but I don't know, kinda splitting hairs but selling points are selling points. I can kinda see having the rear rim closer to under your body as possible for climbing purposes, but not so sure for just a flat time trial or whatever.

All that aside I wish more builders built machines with geometry like the gios compact, perfect for people like me with long legs and short torso, normal frames are a pain to work with to get the fit good, I always gotta stick a short 60mm stem just so I can ride.
