There exist several options that replace the quick release skewers

probably the best of breed is the pitlock skewer. peterwhite & urbanbiketech
both sell 'em

pitlock has the added advantage of also producing a set for securing your
threadless headet -- a not insignicant feature since you could just slide
off the fork and take the wheel w/ it. no fix for threaded headsets, tho.

i use it to secure my schmidt dynohub on my commuter.

and it's always fun to watch the shop mechanic struggle with it.
