Reality Check, pls: use wheel QR as a lateral adjustment?...sprockets2
Aug 10, 2002 11:30 PM
My buddy swears that the QR skewer can be used to change where the plane of the wheel is with respect to the vertical plane of the bike. Want the wheel to this side? Just tighten this side of the QR, want it to that side, tighten the other nut on the QR. He says that if the brakes are rubbing he just releases the QR and retightens in the appropriate way.

Has anyone ever heard of this claim? I am thinking he is nuts. He claims he does it all of the time. He is not putting me on. He was shocked to hear that I had never done this. I told him that when my brakes rub, I adjust the brake. I don't see how it can possibly work, but pls, someone confirm that I am not the one suffering from Fred Poisoning.

Just because somebody has done something and hasn't died yet doesn't mean that it's a good idea or that the guy is smart. Personally, it seems a whole lot smarter to me to adjust my brake once than to have to adjust my wheel every time I put it on my bike. I'm betting he has to make the occasional mid-ride adjustment too.

he's full of it. all he is doing is changing how much threading there is on one side of the skewer. The vertical plane is determined by the nuts on the axle. unless he brings a bunch of hub wrenches with him and messes around with the axle, he's having no effect on the vertical plane of the wheel

That's akin to deflating your tire to clear the brake calipers during wheel removal.

That just seems wrong. I'm guessing that the dropouts are probably the most durable part of frame/fork but that has the makings of one chewed-up dropout after a couple of seasons. I wonder if he files off the lawyer tabs on the fork..

This is related, if the locknut faces are not parallel to each other( slightly bent axle) you can affect where the wheel goes through the brake depending on how the nuts are turned when the qr is tightened. What your friend sez defies mechanical logic and is Fred BS.. But if you take his front wheel and place it in a truing stand and turn the axle slowly you may see movement out at the rim in a lateral direction. So he may be changing the position by accident. Incidentally, Shimano wheels seem to have this movement when turning the axle more than Campy. This is based on personal observation of many wheelsets and I invite those that doubt to perform the axle turn test on their own wheels in a truing stand.

There have been a couple of daft posts lately about using the QR to center the wheel in the frame or to avoid brake rubbing. One even complained that the "adjustment" changed during the ride and wanted to know how to prevent the change. Absolute bonkers. You either adjust the brakes or true the wheel. NEVER use the QR to center the wheel. The bike won't be tracking straight, and it won't stay in place. This ranks right up there with "What wrench do I use to tighten the little nut on the QR - I can't seem to get it tight enough to hold the wheel?"

How about the special wrench to tighten the nut on the valve stem? We could make a mint selling them.

Then give me the list of your customers so that I can sell them all of the replacement inner tubes they are going to need.

What is really surprising is how nasty it gets when they tighten the nut before putting the second bead on the rim and then inflate the tire. Surprise, what happened?
