I think the superbrace guys were interested but no one could/would send measurements. I just got a UCE-style disc fork for my old bike and would be very interested in a brace, but am probably not the precision kind of guy they'd need for measurements. My caliper is big enough to take the OD of the fork sliders and probably the distance between the inner facing surfaces of the fork, though...maybe I should get in touch with them.
Wonder if they'd make one which bolts into the fender mount bosses and could support a properly-drilled plain aftermarket fender...
