85 degree rise stem(5 posts)

I am currently using a road stem with an 80 degree rise, 110 in length. I am wondering how many mm higher my bars will be with a 85 degree stem. What about with a 90 degree stem. Thanks

about 8mm and 16mm respectively. high school trigonometry...

Remember that the stem length is the hypotenuse of the triangle. The rise of an 80 degree stem (7 degree rise) would be 13.4mm, the 85 degree 22.9mm and the 90 degree would be 32.1mm. The additional heights would be 9.5mm and 18.7mm.

You provide me with an answer that proves to be wrong and are condescending in your reply. If it is simple high school trig why were you wrong?
