The pista BB is part made by Kinex. It's the same one as 5 years ago. Remember that the Primato Pista crank was based on a road crank originally made in the 90's sometime. Doesn't make it a bad product; the Record crank has gone unchanged for ages too. Miche do make two other models of BB you could try (so as to get the elusive 107mm iso taper) called the Supertype Ti and Primato Evo Light.
