42 T, 144 bcd Campy ring?(8 posts)

42 T, 144 bcd Campy ring?DougSloan
Jan 5, 2004 9:37 AM
I want to build another fixed with a Campy Pista crank, but want a 42 tooth ring; I want a Campy ring, if for no other reason, aesthetics (a personal thing). I can't find that Campy ever made a 42 Pista (1/8") ring, but of course there are NOS 42 T small rings for double cranksets, albeit in 3/16" width.

So, the question is whether any (Super Record, Nuovo, Athena(?), etc.) NOS 42 T Campy inner ring would work as a single fixed ring, assuming I go 3/16" for the cog and chain, too? Any suggestions? Thanks.

As long as they are both 144bcd, it should work fine. What is your concern?

I'd email or call John at Businesscycles.com. He's very knowledgable about this sort of thing.

... I've not scored the Campy Pista cranks I want for the cruiser yet.

I can't swear Campy makes the ring you need, but there was a 42T 1/8" 144 BCD ring available when I purchased the one for my Pista cranks for the Paramount. I got the 48T in the same line and it fit perfectly. I can't remember the brand ... my Performance LBS ordered it for me from a catalog.
it will work.Arnold Zefal

I've used Nouvo Record road rings on Pista cranks (old and modern), and with NR cranks with short bolts for single ring operation. Will work fine, just use same width rear cog.

Is this possible?Alex-in-Evanston

I know that 39 is the lowest you can go with a 135 bcd ring. Is 42 beneath the theoretical limit for 144?

I think 41 is possible, but I know 42 is nmDougSloan
