Specialized came with a limited frameset for 2015. Epic S-Works World Cup with a Rock Shox RS-1 with Brain. RS-1 sits on the non World Cup S-Works bike for 2015 and on the Era S-Works but not possible to get except with those bikes. Now you can, or almost. Seems hard to get. Includes Roval Contral Carbon SL 29er wheelset and costs a fortune.
Another thing that is hard to get is the new Shimano XTR 9050 Di2 group:
So if you put these two together you get a pretty rare bike:
Super cool in the Gallardo Orange that also is used on the Epic Expert World Cup (outside Europe).
