when will they learn? NEVER just the wheel.
At my building, I noticed a new Trek 3500 -- the model of my new bike. Apparently, the owner had swapped out the quick release and replaced with bolts. But she locked down just the front wheel. It stayed there for three days, and now it's gone. Poof, with just the front wheel sitting there. I feel so wretched for her. Trek 3500 is a mediocre bike, but it sucks to get screwed like that.
When will we learn? Never just the wheel, no matter what sort of skewers you've got, and never just the spokes.
