Team Sky has been known for ‘marginal gains’, trying to gain every sliver of advantage for their team, but a ‘nose ring’ on lead GC contender, Chris Froome seems a bit far fetched. Or is it?

Chris Froome was sporting a yellow nose ring up stage 12’s mountain stage where he lost the yellow jersey to Fabio Aru. On the last steep approach to the mountain top finish line, Froome was seen struggling while Aru notched a 20 second advantage before bonus seconds on his podium finish would be awarded.

The device is called The Turbine, and dilates the nostrils to increase airflow through the nose, allowing the wearer to breathe more efficiently. Creator Rhinomed claims that nasal airflow is increased by an average of 38 per cent while wearing it.

Froome was first seen with the nose ring during the 2014 Vuelta a España, and continued to wear it for much of the 2015 Tour de France, where he took his second Tour win. The device is supposed to reduce breathlessness and help to expel CO2 from the body.

A number of other pros have also used The Turbine, with Jack Bobridge employing it during his unsuccessful Hour Record attempt in January 2015.
