The front triangles are exactly the same between 2012 zestys and spicys, but the rear is a little bit beefed up on spicys, getting 142×12 rear axle instead of 135×10. So you can create both bikes just by changing shocks, but suppose the rear end wouldn’t be quite as stiff if you converted from zesty to spicy. My 2010 zesty is still going strong too, I love it!
