I'm afraid being a skinny butt is not one of my more pressing issues in life these days. Natural padding aside, I haven't had any sit-bone measuring luck, but I think the saddles I tried this summer that felt like a good width were 5 1/2" or so. Up to about 6", but that depends on how flat they are. Actually, my Butterfly is more like 6 1/2, and it was definitely too wide. Anyway, I don't think I need the FX version.

So, it looks like you have to submit info to the company to get the fit number - is that right? I looked earlier in the summer, and couldn't make heads or tails of how to get to the number, but this weekend it looked like you have to email them info.

Misandal: Hey - my DH is from Muskegon! We're actually in the U.P., about 10 hours from there, just north of Calumet. It has been cold, hot, rainy, dry, windy...you name it. It was 85 today, but its only supposed to be 59 tomorrow. About a week and a half ago there were snow sightings - just in the air, not on the ground. Last year we had about a foot on October 13th. My bikes won't be happy, but ski season is on its way!
