Reach & Stack Height of Orbea Carbon Frame?
I'm looking at frame geometries and I've read that the best way to compare one frame to another is with reach and stack height numbers. Unfortunately, orbea doesn't publish those. Does anybody know what they are? I'm looking for info on the 60cm frame.
The details: I have an orbea onix carbon frame, and i'm looking into a cervelo soloist carbon. Sizes 60 and 61 respectively. If I would like to keep my position fairly similiar. I'm currently riding w/ a 120mm stem and I want to know what size stem to buy.
This is all in the concept stage, so i can't actually put the frames next to each other to compare.
Thanks for any help,
B.

Brian,
If I am reading your question correctly, the effective top tube on the 60cm onix is 59cm. The headtube is 212mm. Unless I am being dense (which is entirely possible), add the stem length for the reach (not taking saddle position into account) and add headset stack height + any spacers to get the total head tube length. Maybe your question is more complex than I am making it however.
I have to say as an Onix owner, though, that you are already riding a great bang for the buck bike!

STACK = BB_drop + (Axle_crown_ht + Head_tube_ht) * sin(Head_tube_angle)
REACH = Effective_top_tube - STACK / tan(Seat_tube_angle)
Or you could measure it as illustrated in the above diagram.

WW -- thank you for the education. I knew it had to more complex than I was making it out to be.

thank you for the formula, can you please define BB drop?

The vertical distance the bottom bracket is below an imaginary horizontal line drawn through the wheel axles. The greater the bottom bracket drop, the lower the rider’s center of gravity.

Is there a tool made for measuring these numbers very accurately? I know I can use a level, plumb, and measuring tape, but I wondered if anyone is using something less ancient. I read about a discontinued product called the FitStik that works this way but it's not available for purchase...

No sorry 
. I did post this question (not verbatum) there too. Not sure where it belongs.... then saw this thread and gave it a shot.
Promise I won't post it again in the Bike Mechanics Forum in case you're watching that one too
