• The black side has been broken for a while and has oxidised/gotten grubby, the silver side was holding together until it went exposing fresh metal.

  • Yeah, just that the whole thing is black. I'd have thought it might've been noticeable long before that stage. Like movement, flex, squeaks, etc. What's the scoring on the front side? Where the pedal tore out?

  • I’d have maybe thought that too but bottom line of course is they shouldn’t have snapped at all.

    I’ve seen burrs like that on the front cranks quite often, think it’s just from tightening the pedal up against the crank innit? I wouldn’t be surprised if they are where the cracks have propagated from in this case, ie it makes a good case for using pedal washers.
