So as my build starts to take shape I got a deda speciale seat post and brooks c13 saddle. The bike mechanic pointed out that the carbon (sorry) rails won’t be compatible with the seat post as they should be round rather than rectangular. Had anyone used either of theses items and is it true? Has anyone used these to components together?
