I never broke a pair, instead, mine just sagged. So, I probably stopped using them just before they broke! I was still in "the biz" back then, on the manufacturing side, so I got a hold of pre-production models, etc... Holy soft aluminum! Scott did a bit better when they used better materials for the gen II production model. The first runs were straight 22.2 diameter and came with either 26.0 or 25.4 shims...pretty awesome.
