htat would suck if the 12-27s were out of production. i think thats a darn good range to have on a bike with a double in an area with lots of rolling hills.

I wonder if its true, since only ulterga and dura ace had 12-27 cogs, now they're 10 speed, and the only 9 speed left is 105 and tiagra, which never made 12-27 cassettes.
