    Quick release problem?

    I rebuilt my rear hub this morning - it was disgusting. When I got out to the trails (no, i didn't ride it before I got out there), I hopped on, and as soon as I started pedaling, the right side of the QR got pulled out of the dropout. It should also be noted that I replaced the derailleur hanger this morning. No matter how tight it was, the QR would not hold. I reversed it, and it still pulled out on the right side. Is this likely to be a QR problem? I closed the cam, and then just used pliers to tighten the nut on the other side, and it still wouldn't hold.

    My first guess is that in rebuilding your rear hub, you somehow left too much axle protruding beyond the locknut. This would prevent the QR from clamping onto the dropout . Forgetting to reinstall a spacer would also possibly have the same net effect.

    Thats the problem. You tighten the nut first by hand, then close the cam.

    That's probably it - but I definitely got all the spacers (I always take apart and rebuild wheels over a bin. I hate chasing bearings.)

    I'll see if I can figure out where the extra room came from. Failing that, do you see any issue with just adding another spacer?

    We also tried it leaving the cam open, and tightening with the pliers.

    Originally, of course, I tightened it by hand, and then closed the cam.

    Adding spacers is not an issue as long as there's about 4mm free axle protruding beyond the locknuts on each side of the hub. The key thing here is that the axle should not protrude beyond the dropout faces when the QR is tightened.

    For sake of argument, some Santa Cruz's (not sure if all do) you replace the whole dropout as opposed to replacing just a hanger. So yes, it is possible on some bikes to replace the dropout.

    Also, lugged steel. I do own welding equipment.

    Unfortunately, this is a Specialized, and made of aluminum. I fail.

    I think I may have moved the everything left on the axle just a little bit. I'll take a second look at it in the morning.

    ha! i was thinking of adding "unless you have welding equipment" to my original response, but didnt think someone would try it.

    talk to the SS/FG forum. Those guys will spend 12 hours stripping, debrazing, fitting, filing, rebrazing, sanding, priming, painting, and clearcoating - all so they can open a beer bottle with their dropout.

    That's what I have always liked about steel. Have vertical dropouts? Want horizontal? Take it to the welder! Just out of curiousity, (not including parts) whats the going rate to hack off the old droupouts and slap on some new ones?

    For you? Free.

    You should probably know that I have yet to successfully weld something - still in the learning phase. I don't know what a real welder would charge.

    Try using a large magnet in a tray or something.Keeps things from getting away from you.I usually pull out all the bearings out with a pencil magnet too.

    I used to do that, but I got to rely on it. One day, I built a set of wheels with aluminum nipples.

    I was surprised that half of them ended up under my desk.

    My spin on the magnet is that you will end up magnetizing the ball bearings or any other steel parts, which will attract the usually present steel shavings, etc..

    Update:

    So I messed with the hub for a few hours, never could get that sucker working. Tried a new wheel today - that did the exact same thing.

    For some reason it never occurred to me to check the dropouts:




    Sorry for the crappy picture of the driveside - but it's not really scratched up anyway. The strange thing to me is that the non-driveside dropout is scuffed to hell, but that's not the side it was pulling out on (edit: nevermind. it's pulling out on both sides). Is it possible that's the problem anyway, or is that just what dropouts look like when a bike is used a lot?

    Well try it again maybe you didn't do it right . Tip: Eatadonut while in the act, your dropouts just may verbally thank you.

    your frame isn't the problem, it's somewhere in the wheel or QR still. Take pics of both sides of the hub for us, without the QR. Go ahead and shoot a few of the QR closed while you're at it.
