|with 9 spd, you get a 13-19 straight block, and then two climbing gears. 39/23 allows you to lug up a steep hill at 6 mph, and 53/13 lets you spin out to nearly 38 mph (120 rpm). At that speed going down hill, you'll go faster coasting in a tight tuck. If you need a 12 because you really can spin out a 13 in a sprint, more power to you.|

Bontempi won five stages in one year at the Giro with a 13, but everyone in the US seems to need a 12 or 11.
Most Shimano riders would probably be wise to consider the 14-25 which also yields a straight block in the lower range (14-19).

|Two bikes: 12-27 Ultegra 9 on the Klein, 12-25 Chorus 10 on the Master X-Light. Foothills of norcal, lots of climbing and I use the 23 and 25 a lot (saves the knees). After using the 12-25 the 12-27 is like climbing walls but I don't like the 3 big jumps of the 12-27 (21 24 27).|

|for rolling terrain - 12-23, for flat - 12-21.
for places that point upward, like the Allegheny Mtn range I happen to live in the middle of, 12-27 (I would go with 12-25 but the only difference (DA) are the last two cogs 24/27 vs 23/25 - since both are pretty much bail out range - I make do with the big jumps.)
Rode 92 miles today with around 7000 feet of elevation - not the long grinders you get in CO or CA but the short, steep 1000-2000ft vertical climbs, one peaking at 19%, nice 27, very nice....

|If you can push 53/11 you are racing and sprinting. If you do not, keep away from the 11 and the 12. Hve the 23 in case the curtain goes down in the middle of a climbe.
Keep on spinning

|I'll use the 11 in downhill sprints and I don't have a lot of use for a 25 unless your rolling hills are really steep.|

|I use this combo anywhere I couldn't actually see a true mountain. No big jumps on the cassette to disrupt rhythm. One downside is that if your a spinner that doesn't typically push big gears and the road heads up, you'll be standing to get over the top at a decent speed. I ride a 48/16 fixed gear bike about half the time in the same terrain so a 39/21 feels like a dream in comparison.|

|This set up has been really sweet. On a realtively flat Dayton MS150 this weekend I only had to use the 36 ring once and only because of the 93 degree temperatures on Sunday. A 12-27 would be nice for really steep grades, but the tighter 12-25 block is low enough for me.|

|I have an 11-23 which is great most of the time. For long mountainous rides, I've been known to slip on the 12-25 though.
