Howdy -

I'm feeling kind of stupid here, but I can't seem to loosen the bolt that holds my saddle on.

I need to put a brand spankin' new Brooks saddle onto my mountain bike to start breaking it in, but cannot for the life of me loosen the bolt. The mountain bike is about 15 years old, has seen a lot of use and mud, and given that I'm not the most persnickety of people, hasn't seen a lot of maintenance.

I was thinking WD-40 and an allen wrench that is less likely to snap.

Any ideas?
