In the future, a good way to tell if a bike is metal or CF, if it's not obvious, is to flick the frame a few times with the top of your fingernail- meatl will make a metalic "ping" sound; CF will make a much different, dead, "click", and then assplode. [Well, just kidding about that last part....]

I hope the poor guy didn't trade a good bike for it! (Then again, if he thinks the ZycleFix feels lighter than his old bike...probably not!) -They seem to sell for about $300 brand-new.
