Which Brakeset on a vintage (70's) Paramount Frame?T-Doc

Do I need normal reach or long reach brakes? Will long reach brakes work on the frame?

Some paramounts came with 27" wheels and others with 700 c. I have one in the garage that is 700 and I will measure the reach of the Campy brakes if you wish. If it came with 27 and now has 700, there could be a problem.
Would the 700 be larger or smaller than the 27?T-Doc

Those dimensions are the bead seat diameter and the actual rim outside diameter is larger. I only add this to help avoid confusion for others.

I have a 69 Paramount - so I have faced this delimia

Most expensive - switch out brakes to campy long reach - hard to find

Second - switch brakes out to standard reach and use a drop bolt in the back, the front will be fine - I find campy drop bolts is too short so maybe a diacompe - this is the route I used

Cheapest - lots of nice 27 inch rims available - but tires are an issue
Michelin has made 27 " tires available again N/Mcurlybike

I've got a 27" on the front of my '74, and 700c on the rear, and a set of NOS Weinman side-pulls on it with reasonably generous adjustment available. I can see that there might be a fit issue due to the maybe 1/8" difference in the rim radius, but many vintage brakes had a lot of adjustment in this direction due to having to accomodate both rim diameters.

In any case, once you've gone the vintage bike route, there's a tendency to accumulate lots of parts due to questions like this. Whatever doesn't fit, you eventually swap or sell.

Normal reach is OK on front with 700c wheel, don't know about rear.

That sure does not look like the reach of todays standard brakes which is 39-49 mm .those look like 55 or longer. That is the only way to get that much room between the tire and the fork.
