rebooting this thread has been very helpful. it reminded me of how much i love my BD.com road bike, and of how much i've really wanted to get a disc brake CX bike to turn into my ultimate all-weather commuter bike.
so this afternoon i pulled the trigger and got a
2014 Motobecame Fantom Cross Disc from BD.com. it should be shipped to me sometime next week.
it looks like a pretty solid bike with decent specs (SRAM apex drivetrain, Avid disc brakes, FSA crank & headset, Alex rims), and at only $900, i won't be too heartbroken if it ever gets stolen. slap on some new tires, pedals, fenders, a rack, and lights and I'll be good to go!
