just got a nice dura ace set at a great deal from a friend, but blanked on checking the caliper reach- 4 mm too short for my 700s, as usual... i'd still like to use the set, and talked with my old LBS about fabricating a simple drop bolt since the ones i found online are 75 bucks apiece. any ideas?
Drop bolts were suitable in single pivot brakes, they held the return spring, as well .
the current dual pivot would be a different matter..
without shop resources to machine something clever, look for a longer reach brake.
