Fabio,
Thanks for posting the well formatted pics of your problem. I'm not sure, but the modifications I've made to the geometry may allow it to mount to your road bike. I've increased the dish by 2mm, and increased the fork clearance from the JO model by 5mm. The conflict I see is with the cap on the hub. I may only need to increase the diameter of the cup a couple mm to solve the conflict.
I've never seen a cap like that on a hub before. Is it a rubber/plastic piece that can be easily removed? ie. a "beauty ring"? Does it seal in grease, or just add a streamlined look to the axle?
What is the diameter? I scaled it off the picture at 19mm, but this should clear the existing counter you have. Since it doesn't, I'll need some sort of direct measurement.
I'll see about going to a bike shop this weekend, they might have one I can look at.
Thanks again for posting the pics! I'll see what I can do.
Best,
Tom
