I just made this rack for my GRiSO
I like to have support for my back when long distance riding, I'll fit a pad on it later.
I wanted a rack that could be removed leaving no fittings on the bike.
The same concept could be fabricated in aluminium.
Two lugs rotate from the bottom of the legs and bolt onto the frame where two aluminuim posts are usually located.[You must be registered and logged in to see this image.]
