Well, I'm not a hardcore racer-type, but I'm in pretty good shape and just like to ride alot. I have been riding the SS about 75% of the time since I built it up in Dec. - it has really helped my strength. But I will tell you - Sunrise will kick your ass on a SS - whether you make it up or not. BTW, IBIKEAZ (Scott) does pretty well on it on his Moots 29'er SS. I think he runs 34:20, which is not the same as 34:20 on a 26'er.
I just stick with 32:18 - a little spinny sometimes, but for the most part, it's a nice compromise considering the variety of terrain. I think 2:1 would be too tall day in and day out. And I do not want to keep changing it, though my rear hub (Surly New) is threaded on both sides and I could easily thread another cog on there and flip the wheel around as needed.
Let us know. We can do the Lost Dog/Sunrise SS epic that I've been wanting to link together. And/or other stuff.
