    rear wheel quick release not clamping?

    hello fellow mechanics!

    i'm just about finished building up a friend's 1970's Jeunet and have run into a small problem: the rear quick release doesn't want to clamp down properly. i "screw" it more than tight enough - to the point where it is difficult to close the quick release lever, and still the drive side of the hub slips. the non-drive stays firmly in place though.

    it appears that there is a little more of the axle exposed on the drive side than non-drive - could that be the culprit? should i loosen the cones and shift the axle a bit over towards non-drive?

    thanks for any help!

    Are they hard-chromed dropouts?

    Are you using a "modern" skewer or an old style one?

    And do you have the dropout adjusting screws installed?

    thanks bob.

    no, old-style, (appears to be original) and no - the dropouts don't have allowances for adjustment screws.

    Well, you took away the usual suspect - new skewer in an old frame. And you can't blame it on chrome. I'll say - the dropout is Bent! Actually, I got nuttin'.

    You might look at the axle locknuts, since you're considering changing the spacing. Are the nuts flat, or do they have a ridge or any feature that might keep them from slipping? Sometimes these get reinstalled backwards.

    An old French bike may have had the old style dropout inserts instead of adjusting screws. I see these every now and then. maybe loosescrews or yellowjersey might carry them.

    Yes. If you can adjust the axle so that none of the axle is exposed beyond the dropouts on either side it should cure the problem. Alternatives may be to shorten the axle slightly or put then washers behind the dropouts to increase the spread across the dropouts.

    By exposed axle I assumed you meant past the locknut, not past the dropout. If it's exposed past the dropout than that's definitely an issue.
