Rear Wheel Alignment(3 posts)

Lately my rear wheel has been drifting to the left. It mostly happens on hills and when it moves enough to rub against the frame it makes forward motion very difficult. This started happening after I had changed a flat on the rear. I think I put the wheel back on with the skewer looser than before. I've tightened the skewer 3 times. The last time (this morning) I made it tight enough that it was hard to move it to a locked position.

I'm assuming a loose skewer is causing this alignment problem. How tight should the skewers be?
If you were able to do it right before but not now, my guess isbill

that there is something preventing you from seating the skewer squarely in the dropouts. Even though seemingly tight, the thing is going to slip around under torque on you and immediately loosen.
Remove the rear, check the skewer and the dropouts for anything weird. Reseat the rear. With the rear skewer loose, align the tire and really try to seat it. Tighten.
The other thing I have found with certain skewers is that they feel kind of tight as you push down on the lever, but when you reach the point where they are supposed to clamp down done, the angles on the cam washers are extreme enough so that they actually loosen at the end of the travel (in other words, they feel tight and are hard to lever shut from say 90-120 degrees, but by the time you get to 180 -- all the way closed -- the tension on the skewer loosens). You just have to tighten these more.

I had this problem with my bike - first off, check the wheel dish. If that is OK - check the alignment of the dropouts. These first two points were right on my bike so we changed the scewer from the Bontrager aluminium one to a steel Dura Ace one. This fixed the problem - aluminium scewers can go "soft" - you should have the scewer fairly tight - but you should be able to close it with one hand. Hope this helps.
