I'm having trouble with the 1st-gen Dura Ace left crank loosening up on my road bike; it's loosened a few times so I think the tapers are damaged and it ought to be replaced.
If you have an extra JIS-taper 170mm left crank, preferably but not necessarily one that looks more or less like this, as many old I'd be interested in buying it from you. $10 sound fair? I also have a few odds-and-ends to trade.
