If you are moving forward on a bicycle, aerodynamics are
Studies have shown that when travelling at speeds over 8 mph,
aerodynamic drag outweighs rolling resistance. At speeds of 20 mph
and above, 90% of a cyclist's effort is spent overcoming
aerodynamic drag (cdA), with 30% of a cyclist's cdA due to the bike
and 70% due to the cyclists body. This tell us that substantial
gains in performance can be made by reducing frontal area and
optimising riding position.
Bioracer Virtual Wind Tunnel, now available at Bespoke Cycling,
London, offers us the ability to fine tune your bike position to
reduce cdA and improve performance. The Bioracer system measures
your frontal area and hypothetical speed it takes to maintain this
position. You'll then be coached by a bike fitter in differing
positions to reduce frontal area, with real-time feedback on the
speed, time and wattage effects. Not only can we optimise your
position on the bike to reduce cdA, we can also test various
products (such as helmets) to identify the fastest equipment
available to you.
Bioracer Sessions are available now at Bespoke Cycling. The
sessions length is 60 minutes and costs £150*.

*Only available to customers who have previously had a new or
existing bike fit here at Bespoke Cycling.
