I've had no problems since this but once, with a loaner bike from the shop, I went over a traffic-calming bump and 2 of the 4 straps for the rack came off, the front wheel of the bike slammed into the pavement, nothing broken but seriously out of alignment.

I thought I was going very slow at the time. LBS was very forgiving ;-)

Since getting the new bike I'm giving a roof rack some serious thought, the reason I did not get one before is I'm short and thought it would be a problem. One of the gals at my club has a trailer hitch rack affixed to her Miata. Looks funny but works well and she's more verticly challenged than I am
