I have smx's and tilt chromos. Just use a bearing spacer in between the forks and peg! Chromos are sooo good! And smx forks will not bend, but maybe the axle!
First an foremost, im pretty shure they fit on SMXs. And they shouldnt, Collin made them to fit almost all forks on the markey except Inward zeroofset ones. So you should be good.
