|Seat location formula||HENRY K|

|I removed my Brooks B-17 to try to go back to my Max Flite Trans Am but suprisingly, I missed my B-17. Now I can not seem to get it back in the right location. I remember seeing at one time a formula in which you put your pedal at 3 O'Clock and drop a plum bob down from your knee to the pedal spindle to get the ideal seat location. Does anyone know this formula?|

|This page is a joke, right?! I've always just dropped a plumb-bob from my knee through the pedal spindal for a starting point, making fine adjustments from there. Don't let a mathematical formula dictate where everything should be. Just get comfortable and ride. It'll all come together. Comfort is subjective, it's different for everyone.|

|this page is not a joke! I remember reading about how the fore & aft position of the seat will effect your power (and your knees for that matter). I know that ultimately you need to be comfortable but I just wanted to use something for a reference point that's all. LIGHTEN UP! I thought that this sight was for help not ridicule!|

|Dropping a plumb bob from the front of the knee, through the pedal spindle is a good starting point, but there is no "formula" to go with it. The bike must be level when taking the measurement. The accuracy of this measurement is not great.
If you happen to have an existing bike and a particular brand of saddle that is set up to your liking, a plumb bob can be used from the nose of the saddle to measure the setback from the bottom bracket, to be duplicated on another bike. Change the model of saddle though, and the dimensions are worthless, since no two saddle are likely to sit the same.
There are (worthless) formulas for saddle height (like .883 times inseam). This formula has no way to take into account variations in pedal/shoe stack height, which can vary up to 1cm. I take a rough mesurement from the center of the BB to the top of the saddle, along the seat tube and fine tune by feel, on the road.
