Cannondale Super Fatty DLR80 headshok fork
Sram Wide S Series cranks (S902) with 46T X-Sync ring
Sram Red 2x10 levers
3T Ergonova Team 44cm bars
Avid BB7-Road calipers, 160mm discs
DT Swiss R24 Spline Disc wheels
WTB Nano 700x40 TCS tires tubeless with Orange Seal


What's next:
I might try a Specialized Trigger Pro 700x38 rear tire to see how much faster it is than the Nano (I know it's lighter).

I'm probably moving to 42T front and 11-36 rear - already have the parts. I underestimated the rolling diameter of the Nano 40c, it's a freaking big tire. When I can do 30 mph spinning about 100 rpm in the 3rd smallest cog, that means my chainring is too large.

Finally, I'm looking at winter commuting options. I've found some studded tires from last winter on closeout and I'd rather buy now and hold them than pay full price in November.
