WIND TUNNEL TESTING

triathlete. It’s thus important to
distinguish which equipment will be the
most aerodynamic and thus the most
adapted to seek performance.

And indeed, for Patrick Lange who
already has an almost perfect position,
one of the goals of these wind-tunnel
tests was to determine what would be
the best helmet for him this year and
also his suit and other accessories on the
bike.

What do you measure when
you want to judge the helmet
aerodynamics ?

We measure the air drag but also the
acoustic measurement, the pressure and
the many cameras present in the tunnel
allowing to visualize the air flow.

What is corrected ?

The first thing is the position on
the bike. The more the triathlete
manage to be integrally formed
with his bike, the more he wins
aerodynamics. It’s essential to test
different settings of the bike to allow
to scientifically prove (and not only
on the feeling) what is the the best
position which will less resist the air
flow.

But the measure goes further. Each
accessory (bottle cage, handlebar,
aero helmet...) has an impact on
the aerodynamics of the cyclist/
