so if a rider shows up without a bike and asks you to calculate his seat height based on 96% of his greater trochanteric height
I’d tell 'em to get lost, as I don’t offer my services as a bike fitter.
, what would you measure (step-by-step) on this bare-footed individual?
how would you then generate the seat height no. based on the measurements?
and what instruction would you give to him for him to set up his seat height on his bike to the correct height with the numbers you have given him? (this is assuming you cannot watch him pedal on his bike)
Step 1: put on your cycling shoes.
Step 2: measure from the ground up to your greater trochanter.
Step 3: take the desired percentage of this number.
Step 4: subtract the length of the crank arm.
Step 5: set your saddle height as measured from the center of the b.b. to the lowest point on the saddle to this value.
Step 6: adjust as desired/necessary.
(If step 6 sounds too ‘unscientific’, consider this: for me, optimal saddle height based on, e.g., the approach of Price and Donne actually represents a range nearly 4 cm wide.)
