Yann was lucky enough to grow up in the heart of Entremont valley.. Naturally attracted by challenges, Yann first took part in the local cross-country competition tour where he acquired solid physical and technical skills, which then lead him to the national and international circuits (Swiss cup, World cup, Grand Raid).

After a few years doing bike competitions, Yann shifted its focus towards another of his big passion, freeride skiing, where he also followed the path leading him to the highest competition level (Freeride World Tour). In the mean time, his approach of mountain bike changed to become a way of exploring the most wild areas of his surrounding valleys.


Besides sport, Yann graduated as an engineer/physicist at EPFL. Motivator, finisher and real quiet force, Yann will know how to encourage you and nourish your mind. The perfect companion for an atypical bike adventure.

Originally from Arzier in the Vaud canton, Theo grew up besides the the Lake Leman before moving to Wallis for his scholarship in a sport/study school. There, Theo soon became very mature, having to deal with an intense training, a demanding curriculum and the discomfort of living in an internship.

There, he forged a strong temperament , a vivid motivation to shine on skicross competitions and an instinct to always stay true to himself in an environment under pressure.


Always ready to moove, to go for a ride or to offer his help, Theo is the perfect companion to spend dynamic bike days, full of fellowship and vigilance. His contagious energy will bring colors to your bike days (even grey and rainy ) !
