Riders who break everything and riders who break nothing are of no value in settling the question of a difference in crank durability. Jobst breaks everything. I've never broken a crank. The Redcay I just posted had a different Suntour Superbe crank during the initial 50K miles. I still use it on a different bike. So what. I don't break cranks, any, ever, and as of a few years ago I could do a 12 second flying 200.
I'm looking for the instance where changing a crank solved a breakage problem.
As to everything breaking, I put together about 500 Fujis with Sugino steel cotterless cranksets. I bet they or the Campy 3 arms have an admirable breakage record (like none without a manufacturing defect).
I'm probably a dope, and I know too much about metal fatigue for my own good, but I ride old cranks with reasonable confidence.
