You love to compete in the local time trials and you've done well on your road bike equipped with bolt-on aero bars. But you’ve been watching the pros during the TTs in all the recent stage races on their fancy (and expensive) aerodynamic time trial bikes. And you’re wondering: Should I get one of those or continue to use my road bike? The most important aspect of aerodynamics is rider position, not the aero qualities of the bike. Teardrop-shaped down tubes and seatposts make a difference, but it isn’t significant compared to your furiously pumping legs and wind-catching chest.
