>>3638654In my riding days I wasn't overweight.
My two big perpetual failures were warping chainrings on the crank and warping the crank arms, over the period of a year or so. I've snapped a chain once and it was because I buggered up the master link on a quick repair in an alleycat race.
Those days for the most part are behind me but I still do the local cruises and shit. After I taco'd my ankle my racing days aside from a quick sprint are pretty much done.
>pic related, last MSBike I did, when I still had the SC-6502
