I'm trying to remove the crank from my bike; the crank is an Oval 730. I can't find any specs on this online (even the Oval Concepts site), so I'm guessing it's probably rebranded. Anyway, my Park Tool manual was of little help, as I don't what type of crank this is and the brand/model is not mentioned in the book.

I've removed the non-drive-side bolt, but couldn't get the crank arm to come off. Anybody have any ideas on how to remove this crank?
