Aerodynamic gains: 2016 update and applications to the Tour de France

 

The first article on aerodynamic gains in cycling (frames, helmets, outfits, etc.) was
a great success in 2015. Almost a year later, there
are still significant areas for improvement in this area, and it was necessary to take stock. My time at the Tour de
France and the Megève Time Trial also allowed me to better appreciate the Aerodynamic gains strategic choices made by teams. I noticed that equipment, but also that
managing efforts to ride fast in the right places, are increasingly crucial! I will use the example of Team Sky to present the latest numerical tests that I have from the Tour Int magazine.

We talk about the physical dominance of the Sky (everyone will have their own

opinion…) but we must recognize that there were very few mistakes made in the choice of material. First point: the Aerodynamic gains frame. The Pinarello Dogma F8 is one of the best frames tested in the
wind tunnel by Tour magazine. With a drag of 206 watts at 45 km/h associated with the Mavic CXR 60, it is one of the fastest frames
on the market.

For comparison, the Canyon Ultimate chosen by Movistar drags at 222
watts with ZIPP 404s.
Classic frames: drag at 45 km/h

The latest study on the available wheels shows
that the ZIPP 404 is also
better placed than the Mavic CXR 60. This shows fax lists that the F8 seems like a fast frame! Even equipped with
Shimano C50s, it remains a great machine for riding and climbing since it does not exceed 7 kg!

And in crosswind
The Movistar team
could therefore further optimize its choice of frame and digital & environmental impact should ride with the Canyon Aéroad, tested at 208 watts
with the ZIPP 404, if their sponsorship and allocation allow it.

The 2016 aero/versatile frames

Even if Quintana was often protected, it was his teammates
who were exhausting themselves faster than the Sky team by protecting their leader with a less efficient frame/equipment combination…And for a small
build like Quintana, a non-roller, a frame like the Aéroad would help him ride fast while saving a few precious watts (14 watts at 45 km/h)…Having both versions (Ultimate and Aeroad), I can assure you that
the Aéroad is much faster on the flat and even on hills. During a comparison on a 6% slope and 23 km/h (5.4 w/kg), it allowed me to
gain at least 10 seconds over 10 minutes of climbing with the same clean email equipment and power as the Ultimate (wheels,
helmet, tires, chain…SRM calibrated and removed from one bike to the other)…..a chasm even at an amateur level.
