I would at least try 650b before brazing as it is an easily reverse-able experiment, if you have the spare wheels.
But you will need Thinline pads with R559 to reach the braking area of the rim satisfactorily, IME. Or those Really long centerpulls Dia Compe makes. Braking feels fine to me with the R559's. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
