How does it shift, especially on the 28? You're the first I've heard to install this new cassette, and in that it technically violates Shimano specs, would be interested in your shifting experience.
It's a dura ace rear deraillieur. It should be OK, I'll let you know.
FWIW, Specialized is putting this cassette on a lot of their 2008 models next year with a variety of different RDs (dura ace - 105) and the 9 speed version of the cassette on Tiagra models.
It's a great range for those moving from a triple to the compact. With the 11t gear, the 50-11 is bigger than a 52(or 53) / 12 and the 34/28 combo is pretty much the same as a 30/25.
