Had a guy bring in a bike with a stripped crank bolt in Denver
He said he tried to fix it himself with a cheap hex key from a gas station kit. The bolt was so rounded you couldn't even see the flats anymore. I spent over an hour with an extractor bit and a ton of heat just to get it out. What's your go-to method for a totally wrecked crank bolt?

Used to swear by the extractor kits, but had one snap off inside a bolt on an old Campy crank. That was a real bad day. Now, if it's totally gone, I just weld a nut right onto the stump of the bolt. The heat from the weld breaks everything loose anyway, and then you've got a fresh hex to crank on. Saves so much time and headache.
