Frame squint??????(3 posts)

Frame squint??????Pedro101

The distance on my new bike between the rim and the two chainstays is not the same (about 1mm difference) and I can see it by eye. Is this normal? What is the tolerance?
Thank you very much for any advice
Check the wheel firstOffTheBack

Pardon me if you already knew this, but the first thing I'd do is make sure the wheel is seated all the way in the dropouts, and not mounted a little bit crooked. The next thing I'd check is the trueness & dish of the wheel. Finally I would check with the frame manufacturer - they do all kinds of wacky things these days, who knows, maybe it's supposed to be asymmetrical. If all those check out, you may need a frame alignment.

At any rate, flip the wheel in the frame (cogs on the opposite side from the derailleur) and see if the offset is still there. If it is, then the wheel is properly dished and the frame is a bit off (bent dropout is a possibility). I'm willing to bet that your wheel dish is just a bit off. BTW, you have a pretty good eye if the difference is really only 1mm.
