Wheel and frame alignment problem...(6 posts)

Wheel and frame alignment problem...opencl
Nov 23, 2002 11:43 AM
When I put the rear wheel all the way into the rear dropout, the wheel is skewed to one side. Is this a major frame defect? There are two holes on the dropouts that you can put in screws to adjust the wheel alignment properly though. Is this common? I went out for a ride and the tire scratched the paint on the side of the chainstay off.

You should not be pulling the wheel all the way back in the dropouts. Within reason, the axle should be about half way between the front and back of the dropouts - the dropout adjuster screws are there to help you get the wheel in the same place each time you put it in the frame. When you center the wheel in the frame at the chainstays, it should also be centered at the brakes (always do this with the bike sitting on the ground so that the axle is not cocked on the horizontal). If it is, your frame and wheel are fine. If not, it could be your wheel or your frame. Reversing the wheel (cogs on the left) and repeating the centering will tell you if it is wheel or frame. Why would you take off on a ride with the wheel rubbing the frame?

I centered the wheel and tighten the skewer down. During the ride (less than a minute out of the house), it went back to the old position where it rubbed against the chainstay. I guess I will go get some dropout adjuster screws and center it properly. I will see how it goes... Thanks.
Also the QR may not be tight enough...TFerguson

Try a Shimino or Campy QR with the side lock down lever. The light weight cam types are not as tight. Using a Rolf QR, I regularly pulled the wheel out of the horizontal dropouts. Switched to Ultegra QR and end of problem.

Adjuster screws will not keep your wheel from moving in the dropouts. They are just there to help you get your wheel centered quickly. You either did not have your QR tight enough, your axle is too long and therefore preventing your QR from clamping the dropout face tightly enough, or you have a QR that is not strong enough for the hardness of your dropouts. Many of the aftermarket and boutique wheel QRs are too wimpy to do the job. Standard Campy or Shimano QRs will fix this.

The two previous bikes that I have don't have this problem. I just put the wheel in all the way into the dropouts and they are pretty damn centered. This is the only frame that I have with this off center problem and teh first frame with dropout adjusting screws (my first steel frame too, foco). Thanks again.
