I just ordered a new frame I'm going to build over the next year but don't know how to select which base bar to use.
My old Cervelo p3c came with a carbon Profile bar, but there are so many choices.

I get the width and will go with a 42 as that's what I ride now and it works.well, but what else do I use to select??

Thanks for any info you can provide.
