Thanks. Just got back from a 20 mile shakedown ride today before another arctic vortex hits us tomorrow. I'm happy to report that the bike rides great and is both comfy and fast. I really like the new Fizik Aliante Versus saddle with its deep and wide man groove. No numb crotch or soreness. I had previously test ridden a Cervelo R3 that I liked, but the shop was unable to customize it to my choice of 165mm cranks due to its proprietary very wide press-fit BB shell, so instead they built up a Matrix Rafale Pyro frameset exactly to my desires for about $500 more than the R3. The Zipp 101 wheels are a definite upgrade from the Fulcrum 5.5 wheels on the R3. I went with Ultegra 11-speed for the drivetrain, which works very nicely, although you have to trim the front derailleur on both the big and small chainring to keep the chain from rubbing as you move back and forth on the cassette. I can't believe that someone hasn't come up with a better front derailleur design after all these years.
