I'm shocked. The F too still has ITA .... that's absolutely ridiculous.
I can only assume it is some weird Italian tradition thing.
SKY / INEOS going after all the marginal gains and then not insisting on an update to a modern BB standard after all these years. That's pretty funny.
I guess, to some degree, teams do not choose their kit.
And besides the BB the F12 is a great bike. In terms of racing, and having a team of mechanics and all that, I don't imagine the BB procession would be an issue.
I'm sure Pinarello has some marginal gain rationale for doing it, although it could very well be a support-local-industry situation
