Measuring a selle smp saddle to bar drop
 

Anyone know where you measure saddle to bar drop on a sell smp composite? You can get like 3 measuements, from the back, middle and front... with 2-3cm differences...

Lay a straight edge across the seat. (Rear to Front)

I'd get it from where you normally sit your sit bones on the saddle. There isn't any hard fast rule that I'm aware of for such. Ask the person you are comparing to how they got theirs.

Saddle to bar drop is only useful for bragging. The saddle height is the one thing that really matters for fit.

The number doesn't matter.
