Hi to cold and wet to work outside at the moment so turned my attention to the single saddle. My Model Z project came with the frame for both the front weight/ride adjustable saddle frame and the rear sprung rack/pinion seat frame. I've manage to get the frame apart for cleaning and was surprised that there are no holes in the seat frame to support the normal array off springs I've found on bike seats. I have attached a couple of pictures of the saddle base could anybody tell me what's missing.
Photos aren't but hopefully will help
Regards
Chris
