As @Drago mentioned ... do you have plans to do any competitive racing such as TTs (time trials)? Do you have any aero handlebars fitted to any of your bikes? (an aero helmet isn't going to be as efficient if you're not hunkered down and tucked in to a more aerodynamic riding position)The new giants that I was looking are carbon, according to giant they are worlds apart to ride, I ride in groups at fast paces and do sportives ,
