I have Cervelo P2 white frame with blue logo bike. I think it’s 2015-16 model. I bought it used and it came with 42cm Svet Zero base bar. Obviously previous owner replaced it. Can anyone tell me the size of original bar? I think it should be 40 or 42 and you measure it center to center. I’m thinking about getting Svet R for more drop(20mm) and debating which size I should get. Any suggestions and inputs would be appreciated.
