Ric Hjertberg of Wheelsmith: Cranks lead hazardous lives. Many break "from" pedal cornering/crashing traumas, nasty scratches and abrasion from straps and ankles, corrosion, etc. Pedal eye failures seem ominous but not some decisive majority. Fixing that so that cranks last long enough to break elsewhere, catastrophically of course, is possibly misspent. We used to figure that smart riders replaced their equipment, especially bars, on a prudent basis.
Campag cranks were the vast majority of failures because they saw the really serious miles. Victims were sure not to stray from Campag for fear of even worse experiences. The more of their cranks you broke the more you recommended to others like yourself to use nothing else. ==================================================================================
