Cheap Bike Pedal Disassembly and Postmortem

Late last year, I bought a pair of inexpensive bicycle pedals from a large, relatively well-respected online bike store. They were mid-sized lightweight no-name things made in China, and they were, as I mentioned, cheap.

Fast forward to this spring – a few hundred miles of riding later – and I’m cleaning the bike one day when I notice that the pedals really don’t want to turn. Like, very substantial force is required to make them rotate. I also note that the alloy parts of the pedals are horribly bent and twisted (which I’d noticed before), and that the plastic core of the body on each is bent and distorted, in one case so much that the dust cap on the end has come off (which I hadn’t noticed).

Crazy.

Anyway, I was curious as to just how the pedals had turned to suck, so I finally got around to disassembling them and conducting a postmortem of sorts. Here’s the report, as it were:
