Today I rode 60 miles in the hilly Pacific NW, and it felt great. I think I'm a convert for life: I've only ridden my road bike once since building up the SS, and I see no pressing need to do it again.

There wasn't ever a time today when I REALLY felt like I had to shift. Even the 1 mile, 6% grade at the end was completely doable. Gear ratio 46-18, 69 gear inches or thereabouts.

Obviously this discussion's been done before, but how far have you have you gone on a FG/SS and how do you feel about it?
