Andrew Coggan on saddle height

A recent leg issue caused me to take another look at my saddle height (turns out what I have always used based on feel, zen, and cupcakes is close to the sciency recommendation) and I came across this advice from the bike geek of bike geeks...well, Zinn might give him some competition but here it is anyway:

Step 1: put on your cycling shoes.

Step 2: measure from the ground up to your greater trochanter. Example: 92cm

Step 3: take the desired percentage of this number (96-100). Example: 88.3cm to 92cm

Step 4: subtract the length of the crank arm. Example: -175mm = 70.8cm to 74.5cm

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.)
