When Boone Lennon developed the first triathlon aero bars his goal was to duplicate the downhill ski position for maximum aerodynamics. We’ve come a long way since those early days of the original Scott DH bar. When it comes to picking an aero bar for your triathlon ride, you want to make sure you combine optimal aerodynamics with the ability to adjust the bars for maximum comfort. There’s no point having these aero bars if you can’t stay down on them throughout your ride, right? Don’t worry, though – there are lots of options and choices available these days, so it’s not hard to find just the right bar for your racing and training needs.
Brezza II Nano $1000
This narrow bar (30 cm) is designed for those who want to improve aerodynamics by reducing their frontal area and can handle staying in such an aero position for the entire race. Carbon-fibre compact cradles and S-bend extensions are standard and meet the UCI rules on 3:1 form factor.
Zefiro Pro $525
For draft legal racers, the forearms rest on the aero wing base bar’s upper surface, while the hands and wrists fall into a natural position on the aerofoil handrest.
Aura Pro $400
