I’m hoping to mount my new Righetti seat tomorrow on my ’08 CRG chassis. According to a manual I found, they showed this image for seat mounting measurements. If I’m understanding the image, it’s saying 205mm from the bottom-rear edge of the seat to the back side of the rear axle, but I’m having a little trouble understanding the other two dimensions. Any tips? I’m also still not sure if I should mount up the two seat stays on either side of the seat like the previous owner did for the Ribtect XL seat that’s on there now. Again, I’m a little guy so I’m not sure if two seat stays on each side are necessary.
