Somebody can correct me if I'm wrong but the length of the chainstays on the Norcos don't actually change. Its the pivot behind the bottom bracket that gets moved further back or forward depending on the frame size and this is what lengthens/shortens the Rear its a change of the front triangle that alters the Rear Centre length, not a chainstay swap. Unfortunately for Norco they keep the Seattube/Angle relative to the BB so as the frames grow the SA slackens. Forbidden Druids I believe do the same thing, however they steepen the Seattube/Angle as the frames get bigger to grow the Rear Centre.
