seat angle question... how is your set up?(5 posts)

seat angle question... how is your set up?Gall
Feb 2, 2003 4:44 PM
Hello again,

I know what I am about to ask is a "whatever feels right to you" question. I just want to get the "norm"

Anyhows, where is the tip of your saddle nose at on your bottom bracket. I mean when you drop a line from the saddle tip does it go in the middle, ahead or behind the bottom bracket?

Thanks!

I'm a believer that it should go in the middle... it seems from what I've been researching that often times saddle tilt is more a symptom of a bad fit overall... from what ive been finding out it means often that there are other things that are wrong that are being compensated for...

your post says "seat angle" but you seem to be asking about saddle setback (saddle tip relative to BB). With that understanding, mine is 8cm behind the BB. This is primariliy a function of inseam and pedaling style.

Your body dimensions and frame size (obviously linked). Does it not make sense to you that on a very large frame/rider, the seat would be farther back relative to the BB, where for a small rider frame, it would be farther forward? The starting position for saddle position is commonly known as KOPS, or Knee Over Pedal Spindle. You drop a plumb line from the bony protrusion just below the knee cap (of the forward knee) when you're on the bike, in your normal position on the saddle, with the cranks horizontal. A "neutral" position is that the plumb line falls through the axis of the pedal axle. Spinners might like to be as much as 1 cm forward of that while those with long femurs or who like to push lower cadences might like to be as much as 2 cm behind. This is a completely individual preference, and therefore asking what others are doing is a waste of time unless you know their body measurements, your body measurements, and both your pedaling styles and position preferences. Your asking this question suggests you're looking for affirmation of your position without thinking about the comparative physiology involved. Clearly, except on very small frames, the saddle tip will be well back of the BB center line.
..fit, geometry, saddle style: Don't worry about this. nmSpunout
