Bicycle Mechanics - Road hubs without quick release mechanisms

Do you know of any cassette type road hubs that would have the axle/locknut mechanism found on track hubs? Preferably, the hubs should have cartridge bearings.

I feel that the quick release mechanism makes the wheels much more prone to theft.

You have a few options if you are that concerned. The easiest is something like this: http://www.universalcycles.com/shopping/product_details.php?id=15860&category=160

You could also replace the axle with a longer, solid axle to allow the use of nuts. However, the cartridge bearings hubs I've seen do not use standard axles but some might.

With that said, regardless of what method of wheel attachment you use, if you really don't want your wheels getting swiped you should be locking them to the frame. Even nutted or anti-theft axles won't prevent a mildly-equipped thief from walking off with your wheels.

You can get something like a pitlock

just because it's bolted on, it doesn't mean it's less prone to theft.
You're best served by properly locking up your bike and wheels.

Here's the same basic concept, but without the special wrench - uses standard allen key wrench

(Assuming your wheel thief is as unlikely to be carrying a set of allen wrenches as a crescent wrench)
