"Campagnolo pista crank set. 165 mm arms, BCD 151 mm. They have been polished down by a skilled mechanic in order to minimize wind resistance, so they have a very nice and shiny finish with no signs of logos except for a faint '165' on the back. Visibly slimmer than the standard track crank arms. Nicely rounded edges and a unique look. Black paint in the shallow cutouts, but this can be removed if you want to keep it silver. Dkr 1000 / $200."
Interesting indeed. Somehow I cannot decide whether I consider these improved or destroyed but the asking price is certainly not bad, at least not on today's Ebay rates.
