While I was waiting for Luke this morning to shoot some lines for Empire, I ran into Alan from CyclingWMD. He was riding his freshly-built Nagasawa decked out with a Shimano Dura Ace 10-pitch drivetrain.
Having recently just went to a 36t Sprocket, It was kinda cool to see the two bikes side-by-side with their mini rings. With a 13t Dura Ace cog on the back, it’s actually a pretty good gear. It gives you a ratio of 2.769 and with 38c tires, it’s comparable to 42:15 or 48:17.
10-pitch was a solution Dura Ace came up with to save weight and allow for more direct power. It required a proprietary cog, chainring, bcd and chain. Finding these in such good condition is a tough task, but obviously Alan is up to the challenge. Dude just exudes rare bike porn.

Good seeing you man!
