I measured a 27" wheel in my 700c frame and added 4mm to brake reach dimensions. The rear looks to need a reach of approximately 50-51mm, the front a reach of approximately 52-53mm. I'm on the hunt for some Nuovo Record/Super Record caliper brakes and I see there are some short reach NR/SR calipers. I'm assuming these are 39-49mm and the standard reach brakes would be the ones I want at 49-59mm?
