I believe these are fashioned after the porteur bikes, which used the
additional attach points of the fork crown (as opposed to a single
brake-bolt mount) to add strength and stability at the rack level for
the typically bigger and heavier loads carried on the wider porteur
racks.
I have them on m
How about using a Mark's rack with four point mounting? Should be
more stable than mounting to the center of the fork crown. I have
one of those "other bikes" also, and hacked a four point mount for a
cheap Nashbar rack that stiffened it up write a bit.
