I have: You pick one (A or B or C) left side Stronglight crank arm in 165mm length. I call them 49d's but they may be 57's or even 63's. In any case they are all slightly different and there's pics and details below and you get to choose .... ONE .... arm in trade:
Arm A: Stamped "Depose" and "A - 165". Bevelled 3-4mm along the arm edges. V.Good extractor threads, 9/16" pedal threads partly stripped. A few scuffs/scratches and slightly oxidized along the sides.
Arm B: Stamped "Depose" and "A - 165". Hammered at the back where it's closest to taper. Bevelled 2-3mm along the arms. Extractor threads partly stripped (poor to fair). Pedal threads good - 9/16". Few small nicks and light scratches.
Arm C: Stamped "Marque Deposee" and "165 - 9/16-20" on back as well as "b" and "8". Unbevelled arm edges. The back of the arm (behind taper area) is filed around the edge. Extractor threads good to fair - slightly thin. Pedal threads good, slightly recessed washer groove around pedal hole. Slightly oxidized surface.
All three arms have good tapers. I've never had issue extracting them with a proper Stronglight tool nor have I had any issues with pedals when using them. They haven't been polished or buffed but can easily be "prettied" ... I'll leave that option for you.
I need: A 170mm Stronglight left side 49d arm (or 57/63?). Must be stamped "Marque Deposee" and have a slight bevelled edge along the arms (about 2mm). Not too fussed about metric or 9/16" pedals threads, need good crank extractor threads and good condition arm (no deep scratches). Pics a bonus.
Postage to me in Australia should be about $13.95usd in a USPS Priority Mail fixed rate small box or about $10usd regular air mail simply packaged.
Each party pays their respective postage and otherwise it's a straight swap but can make $ adjust if the condition considerably varies. I'm just trying to balance out mismatched arms.
