I'm not sure about that, but if it doesn't work you can replace the quick-release spindle (the lever plus thin spindle assembly) with a "non-quick-release quick release". See http://www.veloplus.ch/AlleProdukte/...8mmsilber.aspx Then an Allen wrench is needed to get the wheel off, or, for some models, a non-standard type of "key" that only works with the particular model.

QD wheel spindles.
Ned YAW DIS IS GUT...
I have stopped at racks...campus racks,,,where front wheels and sometimes rear were removed or extra chained ...from quick release capacity. depends on the environment... https://www.google.com/#q=wheels+mfg+axles&tbm=shop stopwatch ? |

Compatibility matters because often times the angles on the cones will be different which leads to much faster wear on the bearings especially if used bearings are put in that have already worn to a certasin degree or shape. That can lead to great difficulty keeping the bearings adjusted. It's often just not possible to switch the guts from one hub and put them into a different manufacturers hub. That's why I get a replacement axle whether QR or nutted with the same threads as the one i want to replace. a) cones don't have angles[1] (on the surface that matters); they have curves, as do the outer races b) because of a) there is a wider[2] tolerance for mis-match between the ball race line diameters of the inner and outer races (which differ by some fraction of the ball diameter[3]). c) as the contact between balls and races is (in theory) point it matters little (at the range of angles likely to be encountered with a mis- matched cone-and-race) at what angle the force is applied to either the balls or the race. [1] some extremely cheap cones might actually BE cones, but I've never seen such and would not buy (or use) such tat in any case [2] wider than a curve-cone[4] combination. [3] as the line between the contact points is at some angle to the verticals extending upward and downward, said displacement being necessary for axial location. [4] at least one curve is required, either on the outer or inner race, to keep the balls from falling out. |

For a traditional wheel, provided they're long enough, the threads match the cones, and the axle isn't knackered, it'll work. If its a traditional this and provided that, doesn't really answer the question. My campag QR axles won't work in your hub. Neither will any of the tandem ones. I've answered the question as well I can with the information you've provided. The spindles I'm hoping to salvage from scrap wheels, have cones on them - I'm going to go out on a limb here and guess that those cones on them have matching threads. Easy enough to find out. But I'd check the size and state compared to your other ones. Looks like I should test the wheel nuts for fit before I start taking anything apart. Maybe I need to hope the Cones on the QR wheel fit the axle I want to use. |

You want to just replace the axle - all the cones, spacers, locknuts etc should be the ones which came from the wheel. That way lies least pain. So yes, seeing if the wheel nuts go onto the stub of the QR axle would be a good start. |

Why not just drop the front wheel out when you lock it up, and thread it on the locking up chain where it will fit, next to the back wheel? I've seen plenty of bikes locked up that way, without any apparent problems. Too lazy - also involves unhooking the front brake cable so the blocks clear the tyre. I get grease on my hands often enough fixing things that go wrong. |

-fixing things that go wrong-
when your skills achieve an equilibrium with ongoing reality, you may move into improvement, fabrication and invention. no oil field necessary |

I get grease on my hands often enough fixing things that go wrong. Get another locking cable/chain and lock the frame and wheels together and then the whole package to the lamp post. Cable locks are cheap. Or a length of chain and another padlock. Or spray paint the bike with various colors. I had a mate that did that figuring that no one would steal anything that looked "that bad", and nobody did but whether that validates his theory I'm not sure :-) -- cheers, John D.Slocomb |
