Here are a couple of shots of the front fender mounts on my latest bike model. I’m not working from much reference material for this bike, so these are just off the top of my head. The brighter image is the same as the darker image, but with the exposure increased so you can see the mount in the shadows from the reverse side.
This might also be a nice opportunity to criticize me for the absurdity of creating Subdivision based brake rotors. *wink*
