I have a brand new, still in the packaging Ridley Noah frameset for sale. It is size XS, which equates to roughly a 48cm-51cm frame from most manufacturers. The effective top tube is 52.5cm.
It is the exact paint job as the McEwen rig:

Seatmast has not been cut, and no components have touched the frame. Brand new.
I am considering building it up and racing it, but if someone wants it for $2,400 shipped, its yours. Price is firm. MSRP is $3,150, so save that extra $750 for your groupset.
PM me if interested. I can send a pic, but this frame is literally still in the bubble-wrap.
