Hi folks. I've successfully removed the chainwheel on my mountain bike, and got off four of the chainring bolts, but the last one is stuck. I have the right tools (Parktool hex wrench and Parktool Chainring Nut Wrench CNW), but it won't budge. I sprayed some WD-40 in there too, but still no joy. Worst of all, the slotted nut is getting stripped. What should I do to get that damn thing off?
EDIT: Success! I drilled the chainring bolt right out. Worked like a charm! Thanks all for the help!
