"Do any of you do the filing as a preventive measure?"

After seeing some examples of catastrophic failure of Campag and other cranks on a couple of web sites, they prompted me to examine my own equipment. I did find a stress riser on a Stronglight 106 by the pedal threads. I filed and polished until it blended in smooth.

"My questionis: if a crank has started to crack and the cracks are filed out, is it safe to continue using it? I'm assuming that if the crack and stress riser are removed the crank is safe. Is that correct?"

I would think it would be safe until the next stress riser appeared. I have never had component fail but you never know. Who knows?

Happy Thanksgiving to all,
