A quick up date on my earlier question about using a Sram 11-32 with a Dura Ace 7900 and a compact 50-34 crank. Although I was told it wouldn't work with a Dura Ace 7900 SS, I went ahead and bought the cassette and, to make a long story short, after about 50 miles on the road it works great. It will even shift from the large chain ring to the 32 rear cog. The chain is tight in that configuration so I don't do it on the road.
It sure is nice at 64 to have a bail out gear on long climbs.
