old fluted campag pista cranks.. what bcd?

Hi,

I'm interested in some pista cranks going on the bay, the seller does not know the bcd of the cranks, if they are 144 or 151 bcd then i'm interested, just wanted to check wether they came in any other bcd?

thanks

151 or 144 depending on age

151bcd until about 1968

144bcd ever since.

Is there a stamped date code?

Provide a pic and we'll tell you right away.

cheers, infact i was just checking that, so either 151 or 144 depending on age...

i guess you lot will know the age?

ps the chainring is 3/32, so "if" i win these i will be selling the chainring its 47t, and looking for a 48-50 1/8 chainring.

144bcd

Ok great, i guess thats better, because i understand 151bcd chainrings are a little scarce.

I have a 50t pista chainring in 1/8th NOS as well. And its 144bcd

Can anyone tell me if chain rings off a Campag Pista fit onto a Miche Primato.

Cheers , Thanks for looking.

As per above, it depends on the age. Modern versions are both 144 bcd so should fit.
