1974 Paramount P-10 Part II

This past week I finally tore down the Paramount that I first posted here 3 1/2 years ago :
74 Paramount P-10

As I gathered parts for the re-build I found myself moving towards its original configuration, so as much as I liked the drilled brake levers that came with the Carrera sidepulls, a pair of quick-release levers and centerpull brakes ended up in the parts box.
As found:



I found a 26T Schwinn freewheel and 1974 NR RD, but for now I'm sticking with the 32T and the LeTour GT300

It is a pleasure working on a bike of this quality. Some tear-down photos:

Early 531 decal

Fork crowns are flat on this one. There is no brazed-on pib to keep the downtube shifters from slipping.

Matching serial number on the fork


Noticed this stamp while soaking the stem bolt with penetrating oil.

The brazing transitions are really smooth.

Lugs after a little bronze wool. Still need to use some cleaner wax on the paint.

That is a beauty. I had my friend’s ‘74 stored at my shop for about a year (P13) and always admired that bike even though a size small for me . I rode it and they ride as good as they look. It was very similar to my Super Mondia , same lugs , fork crown etc.

Beautiful bike. I'd be tempted to run a 50.4 bcd TA or Nervar crank to eke out some lower gears. Couple that with the long cage shimano RD you are using and you'll get some good hill climbing gears.

Congrats on this project! I am working on a '75 Paramount, also a P10-9, and mine also has the "P-1" stamped in exactly the same spot on the bottom bracket. From what I have been able to find, I believe this means the frame was outsourced to Don Mainland at Pioneer Manufacturing in Racine, Wisconsin. On another topic, do you have a pic of the 26T freewheel? I have a Shimano on this one, but not sure if it is original to this bike....

I haven't checked the tooth count against the Paramount specs but here is the 1974 order form:




Looks like a SunTour ProCompe to me. The 23T cog is kind of big for the sequence but I haven't check the ratios against the 52/42 chalinwheels.

Photos taken before the shakedown ride:


I don't know why the P10-9 had a 26T freewheel and NR RD standard. Seems like an odd spec for a "tourist" bike. If I don't like the LeTour I'll install a Gran Tourismo.


Lots of room for fenders here. I like these QR cable hangers better than the chunky originals.


Tires are wired-on Pasela 27 x 1 1/4" as the original Weinmann rims are hookless. Not much room here to go wider.

I always hated, and never understood, the 18-23T gap in the Paramount freewheel. I happily run a 14-26 myself on the Bianchi, but it is a 6-speed with a much-used 20T cog, giving me a really good 1.5-step ratiometric progression with 50-42 / 14-16-18-20-23-26.

The proper way to do a 5-speed 14-26 is 14-16-19-22-26, which works well with a 4-tooth drop in front.
