Just because a person owns on of these bikes doesn't make this easy to measure with sufficient accuracy to be of value. For a reach measurement to be of any value, it has to be taken at the exact stack height that you need.

There are better ways to compare frames, when the stack and reach are not listed.

Why not explain what you are trying to do? It's usually more efficient to just compare the head tube length, then compare the TT length, with corrections for any difference in the seat tube angle.

Reach is just the TT length minus the frame setback. Frame setback is the c-c frame size times the cosine of the STA.
