2004 P3 Stem Size?

I was wondering what size my Ritchey Pro stem is that came on my Cervelo P3? Does anyone know what size stems come stock on these bikes? The frame size is a 55 cm if that matters.

Not to be a total wise ass, but why not measure it?

Their web site is ritcheylogic.com.

It is harder to measure than you would think. I just went through this with my 2003 P2k. Measuring from one side I would call it 100mm, from the other side it came out to 90mm. I finally decided that it was a 100mm stem, 17* rise. I wouldn’t be surprised if yours was the same.

This is the one I bought to replace my 100mm stem, it is heavy, ugly and cheap. Also, it sits higher than the Ritchey so I had to take out one riser to keep the bars at the same height. I’ve never ordered from this site before but everything came as promised.

Mine came with the Syntace F99 stem, I thought that was the stock item. Can’t you switch it one for one at your LBS (supplier) or did you order it privately?
