Thanks for the tip! I tried it but was unable to unscrew the bolt with my puny multi-tool allen key, so I did the next thing that came to mind: walk around the corner and down the street to my trusty one-man LBS. I'd like to think to feel better about my pathetic attempts that the WD-40 had longer to penetrate but let's be honest, he has better tools and is a bit stronger so he had it undone in a jiffy.
