I've got a pair of Z12 demos that are in great shape, as in less than 5 days of use on them and only cosmetic scratches to show for it. Brakes I believe are around 120mm. $120 obo
Also, I've got a pair of Rossi Axial 140's race. Great shape, come with skinny brakes and T-plates. $100
Prices are in $CAD. I'll try and get pictures up soon. I'm located in Vancouver, BC, and would rather not ship. Have bought/sold some stuff here and much more on TGR.
Have a nice day
