This past Tuesday I was riding with my girlfriend on her morning commute. I wanted to give my new Mondonico a test ride before getting my teeth pulled. We got as far as the end of 2nd Street when I saw what looked like a crank arm drop from her bike! My first thought was that the crank arm screw had worked its way loose and it dropped the arm. However, when I picked up the piece the arm had broken right off!
I had never seen anything like this. My girlfriend doesn't do anything crazy with the bike (no ramps, freeriding or bunnyhops), except for commuting four days a week on it.
Fortunately, this happened in our neighborhood and not while we were on tour. We rolled it into one of our favorite coffee shops and asked them if we could store it their for the day. I planned to come back later with a set of 105 cranks and BB which I harvested from another bike and put them on.
She has only about 2500 miles on the bike and for something like this to happen really makes us think it's some sort of manufacturing error. Maybe a bad batch of aluminum?
