It's about 3cm above wheel axles. It maybe looks high because Demo's bb is located a bit under the frame and main pivots. I'm not suspension specialist, but this project is basing on FSR design and simple swingarm shock mount, just like single-pivot fully's. It's a bit inspired by my Cannondale Gemini which also has two holes one under another for simple travel change. So it's performance of FSR with maintenance free and simplicity of single pivot. If it would change something, it could have an eccentric shock mount, or a little link that would give more lineal compression.
