everyone’s a critic! 🙂
it sort of had to be like that, i wanted to design a perfect parallelogram. And, because of the shock length, and where it would fit in the frame, and where i could get the top/rear pivot, the length of the links had to be 230mm.
if the top-link was 230mm long, then the bottom-link had to be 230mm long (if i wanted a parallelogram – which i did)
and, i din’t know how much clearance i needed for things like tyres and chainrings and etc. so went a bit cautious.
so, with 230mm links, and cautious clearances, you end up with a long ‘chainstay’.
but i did say, i never thought this would get ridden, i assumed that it wouldn’t work, so didn’t really think about the geometry. i just wanted to get it done, and learn along the way. this frame was nearly made out of broom handles – it’s that level of prototype.
i left geometry to proto3…
