Hi Jawn, You may want to recheck the wheel positioning, or even the frame trueness if your getting the chain touching the tire. I think that something is amiss here,, thats the first time Ive heard of that problem with an ab bike. You may want to check the positioning of the chain tubes also since they may be what is causing that problem. I actually had this very same problem with my ez when I got it, it amounted to just some minor adjustments to the chain tubes to move the chain out more. If youre still having probs after this, take it to a dealer. Good luck.
