Rotor Mount Modification

This part was from a customer who bought a whole new drivetrain and brakes for his old Cannondale F1000. What he didn’t notice was that his Coda hubs were for the old 4 bolt disc pattern and his new Shimano Icetech rotors had the new 6 bolt pattern. No problem. The bolt circle diameter between the two happens to be the same. I machined him 2 new bolt holes in his rotors to match the old pattern.
