Apparently there’s still some room even at a big, soulless company like Specialized to be really, really weird. This will either be a complete flop or shockingly successful.

Edit: pretty sure this isn’t a URT, though. The pivot is just above and behind the bottom bracket, so the rear axle will move around the BB. A URT would have the BB and rear axle locked together, with the pivot in front of the BB.
