I don't think anything came off that flat/leg piece. It looks like the bolt corroded away a bit on the sides. Probably water sitting in there over time, plus road salt during the winters. I checked and that kickstand is from 2013. Warranty is 36 months I think.

It never lined up to be a nice tight fit. It was always a bit loose. I'm trying to think of ways to tighten and protect the new one, like adding in some old inner tube pieces maybe. The bolt was a pain to tighten for how it stick up in the middle of the bike pieces. 1/8 turn by 1/8 turn I remember to get that on.

Heavy load on the bike. I used to go through more regular kickstands, so I invested in this one.
