I'm riding a 05 kona coiler and love it. My buddy has an 07 coiler deluxe frame (including rear shock) for sale. Its brand new never built. Asking 500. Obviously the deluxe is the better bike, but is the frame worth getting? Or is most of the upgrades componets on the deluxe? If i got this frame i'd put all my stuff from the regular coiler on it. I would sell my frame and be in a new frame and offset the new cost from profit from mine. What is a fair price for an 05 coiler frame in great shape? Is this even worth doing? Thanks!
