...What makes this one special is its 'NOS' condition: New Old Stock. In other words the seller, UK bike collector Hilary Stone, was lucky enough to stumble on this gem in unused condition, the prized state for collectors looking for parts to restore period bikes. As it happens I worked with Hilary Stone back in my UK bike magazine days and I remember him (and me, if I'm honest) getting very excited when we stumbled across a set of Shimano Dura-Ace 10 track equipment in a bike shop in Germany. Struggling to conceal his enthusiasm, Hilary negotiated a good deal with the somewhat bemused shop owner for the rare 10 millimeter pitch chain, chainrings and sprocket. "Do you realize these are special parts for track bicycle?" the owner asked. "Yes I know exactly what they are," said Hilary. I wonder what those parts are worth now. Anyone who has more than three grand burning a hole in their pocket and who feels their life won't be complete without a Simplex Record 60 should take a look at the auction here .
