I found that one but there is no info on the weight...

DO you have any good places where I can pick them up at a good price?

if i am not mistaken, i think RB subcontracts Fidanza for their aluminum flywheels, which i think they advertise as 12 pounds, but i don't remember if that's with or without the counterweight.
