>Anyone hear of high quality steel cranks breaking?

Um. . . yes. We actually talked about this last month when a bike went up on Ebay that had a broken steel crank. I've personally brazed on 2 pedal eye replacements in the past. Steel cranks do break, good materials never overcome poor design. I've also seen a few pair of modern broken steel cranks too. Steel has a fatigue limit too it's just not as low as aluminum. I do believe that well designed steel cranks are much less likely to break though. enjoy, Brandon"monkeyman"Ives
