Hey Scrod,

Lately I've been paranoid that my rear wheel isn't perfectly straight in the dropout. This is important for chain-line and general smooth rolling obviously.

I line it up with seat tube and that's that for now.

Is there a way to verify if my seat stays and drop outs are straight and kosher? This is something that would be useful when buying a new frame obviously. I know that a little imperfection is likely and the stays compress when you tighten the axle nuts. I also ever so lightly tightened up the cone nuts/lock nuts on both sides of the rear hub with cone wrenches and eye balled the axle of the hub to make sure its even.

I guess i'm just interested if you eyeball it or if there is an effective way to measure to see how proportioned the rear triangle of a bike is built.
