I rode from Vail to Breckenridge in the Colorado Rockies, which from Vail to the pass, is as steep as a climb can get, i never went to the small ring in front. If you legs dont have the power to turn the small ring in front on a double, then stick with a triple, otherwise it's useless.
lol, you're a better man than me... I did a 50 miler this weekend on hills that were 3-5% grade, nothing too crazy (it's Texas so no mountains here), and I STILL needed the small gear on some of the longer and steeper climbs. Overall, I'm pretty happy with the new cassette because I felt more comfortable shifting between the middle gears because they're closer together.
