When it comes to campy bottom brackets, I always find myself confused.
So I'm in search of a bit of wisdom.
The first problem is that I am trying to piece together a campy pista
BB. I have a 68-P-120 spindle and recently came across a set a thin wall cups- which I believe are the correct cups for a pista BB- No?
My understanding is that Campy Record (on topic, not c-record) Pista bottom brackets use 3/16 ball bearings. However, when I installed the
BB in the 68mm shell, the adjustable cup went all the way in the shell
and was still loose. So just for kicks, I tried a set of campy 1/4 balls and voilà, it fit perfect.
So where did I go wrong? Were bearing sizes between NR and SR pista bottom brackets different. Perhaps mine is NR and I was using SR bearings.
Thanks in advance for everyones help. While it may take me sometime to
respond, I'm always very thankful for the advice I am given- and if for any reason I've forgotten to thank anyone in the past for their help or advice, I'd like to send out a big "thank you" now. It's not as personal, but better than not.
