I removed these pedals from the bike from my father in-law. Quite rusted and the left one with a lot of play. If it didn't say they are Deore LX, I would throw them in the bin, but... Is it worth restoring? If so, do you know of an online guide on how to overhaul them? The axle is hard to reach without removing the cage, but the cage is pinned, not screwed, so unlikely I can remove it.
