We have a front and rear in ceramic that fit many of the 12s.

Front is 7x17x5...rear is 12x21x5

If that Picco is like the new Picco's, the front bearing is smaller than all others and I know of no one that makes it in ceramic except maybe for Boca.

Thanks guys.
Yes the Picco bearing is a 6mm ID. And I have not had any luck finding any replacement for it. I don't really want to pull it out unless I have a replacement on hand, so I haven't been able to measure the OD

Anyone else have an idea.

I measured the od of the crankshaft for the O.S. TR .12. It's 10.95mm, so the 12x21x5 bearing is the wrong size for the rear bearing. Looks more like a 11x20x5.
