Mathias Fluckinger's Prototype Dual-Suspension Radon - MSA XC World Cup 2017

...

Mathias Flueckiger brought a custom made Radon dual-suspension prototype to race the Mont Sainte Anne cross country course. The carbon 29er is yet unnamed and there are no official plans to put the design in production—yet. Mathias says that the bike is a one-off racing-only machine that was made in Germany to perfectly fit his body and riding style.
To boost stiffness, there is no provision for a front derailleur, so that the frame could be wider near the bottom bracket and also lengthen the swingarm-pivot axle. The size, says Mathais, is somewhere between a small and a medium (about 17"/432mm at the seat tube) to fit his five-foot, seven and a half inch (172 cm) frame. Mathais was happy to add that no expense was spared to turn his custom Radon into the ultimate cross-country race bike.

A lot of action near the left grip: The Fox iCD rotary remote lockout switch; Shimano XTR brake lever; and inboard, is the Shimano Di2 shift control.

More tire and mud clearance than most cross-country race bikes use is a hint that this is not Mathias' first rodeo.
