My old Schwinn had a post so stuck I thought I'd have to cut it out. I used the same trick with a store brand cola, and it actually worked after two days. That feeling when it finally twists free is pure relief. You're not alone in the weird bike repair club.

Heard coke works because the acid eats the rust.
