07 demo reach/ stack wtf?

I'm trying to compare what I'm riding, 2007 demo 8 Medium, to potential new bikes using reach and stack measurements.
I think the whole reach/stack idea makes a lot of sense. So I used a plumb bob and a tape, and measured my reach (the main measurement I'm concerned with) both ways. First time, hung the string through the center of the bb, and measured to center of ht holding things as square as we could. I came out with roughly 17.5" reach, for a medium which looked to be quite large compared to other bikes, even newer demos. Re-measured the other direction, string from center of ht, measured from center of bb to string, and same thing.

Does anyone know of an official source of reach/stack for the older demos in a medium, or can anyone confirm/deny my findings based on their own 07/08medium demo?

I'm asking because 17.5 is freakin' huge-- a 2011 large demo 8 is 17.6" for camparison. I'm trying to makes sure I'm right so I can geek out looking at new frame numbers and have an accurate comparison.

Thanks for any help!

I can't even remember the 07 Demo but are there geometry adjustments (including the fork) that could effect the measurement? Are you also sure you're on level ground?

I'm sure you've thought of this stuff but...

Looking at the archive it seems as all the top tube measurments has gotten shorther so a shorther reach could be quite possible.

medford, or
Demos have always had long front ends with the short chain stays. I have a small 07 d8. I bought a small based on the long front. Still kinda wished I had a medium. Just doing quick tape measurements on mine I think your pretty close.

Thank you guys- I think of myself as liking bikes on the small side, and at 6' tall, I thought a medium was "smallish".
So this came as a suprise- looking at the LARGE tr 250, my medium (17.5" reach) makes it look short (16.21")

I'm looking at buying a FREERIDE bike, so I'm comparing between the TR250, SX Trail, and Kona Entourage.

Anyone have any time on an entourage?
