Seat height/width question
I'm trying to decide if my seat is the right height. At the bottom of the stroke my knee is just a little bent but I can straighten it and lock it with very little movement, it doesn't feel like my hips are rocking. Does this sound too high? Another thing is that it feels like my legs are rubbing against the side of the seat but I'm trying to decide if the seat is high and I'm reaching or if the saddle is too wide. The bike I'm riding is an old Gary Fisher mountain bike with the handlebars about an inch lower than the seat. I got the seat from my old bike which had the handlebars about an inch higher than the seat. The seat is also an inch or two wider than the one on my road bike so I suspect it's a little wide.
Another thing I'm wondering is a seat height calculation I saw. It said to take your inseam (about 35) and multiply it by .885 which gave me a recommended seat height of about 31 inches. When I measured my current seat height it was around 37 inches already and I was going to raise it more because it felt too low! I had my wife watch me pedal and she said my feet are about parallel to the ground. Am I just doing something wrong? I measured my inseam by pulling a book up to my crotch and making a mark on the wall, then measured it with a tape measure. I tried it several times and always came close to the same number.
