Saddle Height - is 0.883 rule too high?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Saddle Height - is 0.883 rule too high?

I usually avoid posting in zombie threads but... I can't help it this time.

Every runner has a different natural gait, a different natural stride, a different upper body position as they run.

Every cyclist does too.

Some of us are super picky about fit, some of us could ride in a host of different positions and never care.

Whatever "rules" there are, you'll likely hear more from those who are exceptions than those who the rule applies to.

But that's what keep forums alive, so…

0.883 is hilariously precise, considering the amount of inherent measurement error in measuring the inseam as well as measuring from the "center" of the crank to the "top" of the saddle, neither of which have true registration surfaces.

This automatically discredits the rule.

Sure, just round it up to .885 and you should be good.

I think that the rule's precision had been meant as a joke from the beginning, and that got lost somewhere along the way. But in the end you wind up with a number, and the number is OK, nothing to get hung up about.

My bike fitter is a believer in the .885 rule. This is known as the Greg Lemond seat height measurement. There is also the 109% of inseam from the bottom pedal spindle.

Both .883 and 1.09 give roughly the same results and are roughly OK for me - different pedalling styles, shoes, pedals, saddle setback, etc. can alter optimal saddle height IMO.

Course the ideal height is also dependent on the shoes and type of saddle.
Right there this calculation doesn’t take into account foot size (the length of your foot), which will figure into the effective length from hips to the ball of your foot on the pedal. Maybe a place to start, but unlikely the end point for many/most riders.
