25 years in the bike biz, never saw a Cinelli break that I can recall. Creak? You bet!
Broke 4 bars myself: 1 Pivo and 1 Beleri (sp?) drop bars, one GB semi-flat bar ("All-Rounder" I think it's called), one TTT semi-flat bar, similar to the GB (Neither of those was a mountainbike bar; they both predated the MTB phenomenon)
