Jay:
After numerous saddle tweaks, I found that all my saddles ended up at 67 cm in
height from the BB center, and my PBH is 78, so I'd say the Riv formula works
really well for me. I measure through the center-line of the seat post. Moving
the saddle back or forward changes the measurement due to the angle I pitch the
saddle at, so yes, I have to raise or lower the seat post if I slide the saddle
around. Also, if I wear thick soled shoes (like KSwiss hikers), I have to
raise the saddle for efficient pedaling. My standard is based on Addidas
Sambas, or my Summer sandals (Teva and Nike) which have the same sole thickness.
Rather than tune your saddle to numbers on the riv site, you might try small
changes in height to see where the sweet spot is for you. That's giving you an
efficient stroke (you feel all the leg power going into the pedals when
climbing or accelerating) and you have no pain in front and above your knees or
just behind your knees. Then see how your numbers compare. You can of course
just try the riv suggestions and see how they go, and tweak from there. small
increments though regardless.

Subject: [RBW] RBW Saddle Height question
Hi all:
The RBW method for determining saddle height is PBH - 10 to 11.
How many of you use this formula?
Do youadjust it if you place the saddle all the way back on its rails?
(Related....don't laugh...where does one measure the top of the
saddle...the area where you sit, the area right over the seat post?)
