Ok I just tried to measure my hip to knee…but I’m not exactly sure where to start and end…the tape was bending…I think I got 18", but that doesn’t seem that long, considering…
I’m 5’9", not freaky thighs, but I would say it’s a big contributor to my height. I like a pretty short stirrup. I can ride in standard flaps but it’s always just a little uncomfortable, with the knee poking over or the leg getting pushed back. In higher end saddles with flap options that I have ridden in, the forward flap feels right.
I bought a used Legacy XP a couple of years ago. From what I gathered there were no flap options, but the cut of the flaps on that model as a whole was forward. Since the price was right on the one I was looking at, I decided to go for it, even though it was only 17" and I figured I should be in a 17.5".
I love it and do not regret the purchase at all. My leg (and butt and crotch, lol) feel right at home in it! If the price is good, I Would say try it.
