Using the 109% method takes the crank length into account. If you then realy want to measure from the centre of the crank you can simply deduct the crank length.
It doesn't matter because it produces results which are centimeters away from the optimum (and that's where 3-5 mm play role). In my case, that would be 27 mm more than what I have after numerous professional bikefits
6:04 for some reason many get this wrong. The test is not to be able to sit up with no hands. In a perfectly balanced position you should be able to bring your hands behind your back without changing anything else - i.e. keep the torso angle as if the hands are still on the bars. For that you also must be pedaling reasonably hard or your torso will be sinking anyway
I measured my inseam to size my Canyon bike and then set my seat height by feel. I used the formula here to see how accurate I was and I was bang on, down to the millimeter. Now only if there was as precise a way to measure fore/aft.
This guy just explained all methodes instead of one 🎉🥰🥰
but WHERE on the top of the saddle? That can change the measurement drastically
The second method takes no account of crank length.

@@chrishawyes1476the proposed 109 % method gives me an error of 39 mm, lol
its def been taking me a lifetime...
Man I’m short af, ima feel like im flying with my saddle that high😂
Not the right way to use a metal tape measure.
If you can’t handle the heat - and let’s face it ; you’re talking about nuclear armegedon - the GET OUT OF THE KITCHEN.

Great vid! Precise and clear 👍

Nice video. Should my palms hurt after about 30 min of riding. I have gloves.
Another great little video on the basics (and with a world pro!). Thanks TPC!
