Having spent a year building up the Ridley X-Fire in my .sig, I realized it wasn't the bike I was looking for. So, I sold it and recently got this Santa Cruz Stigmata CC from a teammate.
Much like me, he bought it, spent a bunch of time and money building it up, and decided it wasn't for him. Sucks for him, but great for me. It's only got parking lot miles on it.

Weird but True
* Despite a complete Shimano build, my friend decided to put a Campy CX crank on it. Shimano *really* needs to release that 46T Dura Ace chainring
* One can successfully run a Dura Ace (short-cage) rear derailleur with an 11-32 cassette (so long as you limit the size of your front ring)
Plans:
* I'd like to put some wide tubeless gravel-friendly tires on there so I can play on-road and off.
* I'm going to change the rings on one of my compact Rotor SRMs to 36/46, change the BB, and install the Rotor
* Sometime... Di2 again (like on the X-Fire)
