Buying Cervelo P2 vs P-Series
Cervélo advertises the P-Series to have less drag and weight than the P3 (and therefore P2). Which components/groupset are installed on the two bikes? What’s the overall cost? 1k$ is not that much of a difference when the bike costs several thousand.
Are you riding in bad weather (and/or hilly terrain) and can make good use of the disc brakes? One thing I also like about disc brakes is that you avoid wear on those very expensive aero wheels.
If the P-Series comes with electronic shifting I’d definitely pick it over the P2.
