For Sale: D.Salmon Complete Track Bike

101 BCD, quite a few manufacturers were using these 3 arm patern in the past including Campy (I think hilary had a set of NOS for sale not too long ago) and Chater Lea :) Saw some used chainrings for sale at a jumble sale for chips.

More info on the cranks? BCD etc. Chainrings hard to find?

Sorry. Don't konw about the BDC, that kind of chainring is not rare but many people think that this cranks are crap because there's only 3 arms... so you can find some by asking to somebody or to hipster who don't know that this chainring are quite stiff and well made, so they sell that kind of charing for nothing.
