Q: saddle nose gap to BB center?

General question for everyone, how far back is the nose of your saddle from the center of the BB?

(Suppose you dropped a blumb-bob down from the nose of your saddle, then measured the distance horizontally from the BB back to the wire)...

?

This will be totally different depending on the rider and the saddle.

Between 8.5 and 10cm, 91.5cm inside leg.

This can vary a lot depending on the saddle, though, so it's not that meaningful. A San Marco Regal at 8.5cm puts my butt around the same position as an Aliante around 10cm...

Incidentally, an easier way to measure this is to place the front wheel against a vertical surface (pillar, wall, whatever), and measure from the saddle nose to wall and BB to wall. Setback is the difference.

I changed to a zero setback seat post and moved my saddle forward A LOT.

now I am 2 inches back from the bb center and I seem to have more power like that.

We'll see how it goes.

50mm on the SLR
55mm on the Toupe

both saddles are 729mm from the BB center, as measured to the surface of the saddle in line with the seattube.

I was just thinking about asking this yesterday.

Mine is 5cm and I have the saddle height at 91cm (measured from the pedal platform at full extension to the top of the saddle).

80cm from BB to top of saddle. Set back 7.55cm. Yes, 1mm makes a difference for me.

Really. People come into the bike shop looking for parts in American sizes and I usually say "These are bikes, not Fords. We go by the metric system."

I like it forward and low

Have had it at 12cm when I thought it was cool to ride like a Cadillac.
