I have a carbon high end dual suspension bike - or just the frame if that's what you may be willing to trade - that I would like to trade for a hardtail.  My bike/frame (2013) is really just perfect but the story is that I began riding hardtails and to be honest I'm evidently different from most riders in that I just don't enjoy dual suspension.

PM me if you have something you'd consider trading and I will give you my bike info.
