re: fork and dropout change on Surly CC for disc brakes
I saw some pictures of a Surly CC with disc tabs added, stock fork and stock dropouts left in place:
- Front fork had disc tab added to front right fork blade, compensates for rear facing dropouts
- Left chainstay had disc tab added to top to chainstay, stock dropouts left in place, allows standard rear rack.

I looked at my frame (Schwinn Sports Tourer in picture above) and I could add a disc tab to the chainstay, I might have to loosen one of the caliber bolts to remove the rear wheel. Would allow me to use my large collection of regular rear racks too.
