How did you end up with that saddle height? Were you fitted that way, or is it just one of those "I think it's supposed to look like this" things?

I'm 6'2", with a pants inseam of 32", so I guess my cycling inseam is about 34-35". I was fitted with a seat height of 80.7cm. I haven't done more than 105 miles on a ride, but it works for that, and I expect I could double that distance and it would still work...if I could do a 200+ mile ride. How do you feel on long rides?

I'm guessing that you're way too high, and that 841mm would put you in the ballpark. The only way to be sure would be to take yourself and your bike to a professional fitter and have your bike fitted to you. It's a pretty good chunk of change, but it's one of the best investments you can make.
