This would be difficult, considering the Z line was nixed about 2 years ago.

I have ridden the ever loving crap out of my 2013 z85. 20k miles. From intro for a fat guy to road racing and ultracycling. Yes, I have nicer bikes now, but none as comfortable. It's a great frame. I have upgraded all kinds of parts, wheels, crank, bars, etc etc etc. I would be totally comfortable paying 250 for it. Pull the 105s off, sell em, and use the cash to fund an upgrade.
