Interested in a formula to calculate what the difference in drop would be between these two stems? 110mm -8 degree vs. 100mm -17 degree.

Thanks.

I haven't checked the second one, but the first one from habcycles can simply be downloaded to your computer. Right-click. Click Save As. Go from there.

Gee, I use good old trig. The stem angles in road bike terms are 82 and 73, so the angle with the ground would be about 9 and zero, with a 73 degree HTA. The rise of the 82 would be 110 x sin9 = 17mm and the other stem has no rise.

82 and 73 it is then.Thanks for the trig! I appreciate it.
