Lighter-Where it's machined now is made with cast instead which makes it lighter and stronger
Bearings instead of Bushings which will make it a little bit smoother and faster rebound
And some small Geo Changes and different paint
Geo changes were mainly to reduce what was apparently an overly agressive kickback in the pedals when landing drops. Bushings and the bolts with them had wearing issues, and a frame that will have possibly unreplaceable parts push this tempting offer out of the realm of possibility for me. Cant wait for a consumer product to become available though.
