Frame Design: Stem angle
I know it’s a little late, but I wanted to make one more point about frame design and how it is impacted by the stem angle on the frame. Davide wanted an 84-degree angle for the Velvet because he thinks it looks “very aggressive and race oriented.” When we design with a lower-degree stem, we use an extra spacer to add the ability to adjust position in the future. This stem angle also elongates the head tube and increases slope when compared to a design with a 96-degree stem.
Why does this happen? Below is a picture of 2 versions of the Velvet: they have the exact same rider position, the only difference is the stem angle used.
While the pictures do look similar, the 96-degree stem results in a head tube that is shorter by 1.3cm, a seat tube that is shorter by 1cm, and 3 degrees less top tube slope, though they have the same amount of standover clearance and the same rider position. These are subtle differences, but Seven riders have specific requirements, and we are happy to be able to meet those requiremetns, whether they are aesthetic or positional.
