DIA-COMPE Center-Pull Braze-On Assembly Kit (for One Brake)
One set of springs and aluminum plates to mount center-pull brake calipers (DIA-COMPE DC750 & GC610) to braze-on mounting posts. Will work with vintage DIA-COMPE and Weinmann brakes as well as MAFAC (use only aluminum plate with stock MAFAC springs).
Two sets are required for front and rear brakes.
Note. The brake mounting studs on our frames are M6 Bolts X 11mm deep. FYI standard cantilever studs are M6 bolts X 16mm deep.
The bosses on our VR frame are M6 Bolts and will fit all regular long-reach center-pull brakes (typically 63-75 mm), Weinmann 750, Diacompe (DC-750) , and Mafac Raid. They need the DIA-COMPE Center-Pull To Braze-On Assembly Kit to make it work. The kit comes with replacement springs for Weinmann and DiaCompe brakes. Mafac brakes only need the plates and reuse the existing springs.
The Rene Herse brakes are compatible with our VR1 and VR2 Frames

Dia-Compe GC700 may work based on the reach we don't have any customer confirmation.
We haven't been aware of anyone who has disassembled and installed Paul center-pull brakes. They could work as they use a M6 bolt.
