Here's a picture of a new seat in development.
I have had this seat around for a couple of years and been slowly making changes until I was happy with how it fit me. The original idea was to build my own highracer with an integrated seat and tailbox, but realising that I would never have time to do it, I ending up buying one instead. The seat differs from other composite seats that have two large ridges down the back for stiffness and are pretty flat crosswise on the front. I found that these seats never seemed to fit me well as I seem to need a groove in the middle of the front for my back. In the picture you can see the groove down the middle and a small stiffening flange all around the outside of the seat. The mould has wide flanges on it so we can either infuse it or use our proprietary bagging process. It may well be quite a while until I get to try the seat out. If it fits in the Borealis it could reduce the weight by a good part of a kilo and lower the COG a bit for better cornering. In Version 2 if I end up a bit lower the Flevobike roof will work better with my helment on. Right now I fit without touching but if I turn my head I just contact the roof with my helment.
