Subject: [CR] Drop bolts for Mafac Racer, Competition brakes?


One of the biggest issues with our Peugeot UO-18s was that Mafac Racers no longer reached the braking surfaces of the 700C alloy (OT Mavic Open Pro) rims that replaced the mixte's original steel 27" Rigida "death-in-the-wet" rims. It took me a long time to find two sets of used Weinmann 750 centerpulls, and I still have the original Racers in the garage. And since (in all likelihood) I will be going through this process again with another "perfect-fit" UO-18 Mixte, I'd just as soon use up the inventory I have this next time around. But I still need another 5-8 MM of brake reach out of those Racers.

Have any of you ever heard of, thought about, designed, made, seen, purchased, or used a drop bolt (similar in concept to the ones used for Campi and Suntour Superbe brakes) for Mafac centerpulls?

My initial pondering (while waiting in the lobby to report my bike's theft to the Alameda Police Department) lead me to believe that such an item would actually work and might not cost too much. And a UO-18 mixte only needs a few silly millimeters of drop (5-8?) to make this concept work.

Thanks for your responses.
