It is a 12 - 30 cassette actually. Works fine with the compact double derailleur. And while being fast and responsive, it is definitely an all day ride. We had a 70 miler with 6500 - 7000 feet of climbing over some rough roads and I was fine after. Definitely felt better than I have the last few long rides with my backup bike. I honestly cannot imagine carbon feeling as light and responsive as this.

Here are some glamor shots:

I love the headset picking up the bit of orange in the frame:

Carbon is good; Record is better:



I was afraid the new Record shifters would be noticeably larger then the old ones, but they are not. And you can do a very cool aero position with them, bracing the palm of your hand on the horn and leaning down on the bar. Very stable.
