After racing on Friday night, I found that you can quickly remove a roof rack just by driving into a too-low parking garage with the bike still on it!
I knew I was going to do that one of these days, it's just so easy to slip up once and forget that you have to break your normal habit of coming home and parking in the normal spot. I typically will park on the street and then bring the bike to/from the aparment first.
The whole thing came off in one piece, slipped right off and fell backward. Apparently the hanging bar that denotes the max height grabbed the bike by the saddle and pulled the bike, carriers, and rack off cleanly.
Everything looks all right - just a couple light scratches on the car, chrome piping dented in a place or two. Even the clips from the rack don't look too bad off, they may not even have been bent past their elastic limits.
I am wondering if my fork is bent backward now, though, although from the way it was pulled off, I'd think it would have been bent forward if at all. The stock pictures online look a little more forward than mine, but comparing it to older pictuers of my bike looks the same. Seems to handle the same. There seems to be a lot of toe overlap, but I had toe overlap before, and I'm not sure if there's a little bit more now or not. Maybe I can check it out when in position on the rails at the track tonight, see if it seems different when getting balanced on the bike.
All in all, it was a pretty interesting event. I haven't tried to put the rack back on yet - I figure I'll give the car a good wash first. Luckily it wasn't a brand new or immaculate car or anything, so a couple small dings don't mean much.

I guess it's fortunate I don't need one, though, as the wallet would definitely feel that!
