Thanks! It's a 2010 frame that was available at the time with drop bars and discs. They have a split drive-side dropout for a belt so you see a lot of them setup that way, but they also came with a Tiagra drivetrain option. I got this one in trade as a frameset and it's been through a few iterations, with that pic being what it is now (except for the crankset, which is now 6800).

It was designed for 700c wheels but I went with 650b instead. The current build is:

King headset
Shimano Pro Vibe stem, bars, & seatpost
6800 crankset/bottom bracket
6700 rear derailleur
6700 front derailleur
5700 shifters
Tiagra 12-30 cassette and 4601 chain
TRP Spyre brakes
WTB i23 650b rims to XT hubs
650bx42 Compass Babyshoe Pass tires
Adamo Road saddle
