Marketing use to tell us that aero equipment is always the best for every triathlete, reducing drag, save watts, save a lot of time on the big leg etc etc etc....
i don't want to pay attention to marketing . I prefer a pragmatic approach.

Just have the choice between mavic cosmic carbone sl (1.850 kg but aero) and shimano dura ace c24 (1.3kg), for the Triathlon des Lacs in Troyes, 83 kms for the bike (75% flat), considering my level allow me an average speed of 33 kmh...
So Cosmic carbone sl, advantage or not ?
thanks
