Let me take a different tack, since at least one person seems confused about my position.
I live in Colorado and, until comparatively recently, I was primarily a road cyclist.
I've ridden over most of the passes, in the state, at one time or another.
I've ridden up Mt. Evans a time or two and I've ridden up Trail Ridge Road many times.
I've ridden super Flagstaff, if any of you know what that is.
I don't think I've ever used a gear lower than 32T front by 28T rear.
A 1:1 gear ratio, like a 32X32 seems excessive to me. I'd rather grind it out in a bigger gear, even if I have to stand.
I realize, with the bigger tires on a 29er and the higher weight. I might go even a little lower than 1:1, but I just can't see needing or wanting a 32X51 low gear.
That's me. I was just wondering if I'm the only or if others feel that way too.
