Facts

160 MM / 150 MM 29" / 27,5" IPU900 Carbon Push+ 864 Wh / 36 V / 21.700 Cell / 3.580 g / QR-Button DJI AVINOX M1 105 NM 22.0 KG (ULTRA)

The R.EX represents the next evolutionary step in the ROTWILD world.

Versatility is the name of the game here: as an all-mountain version of the World Cup Race Enduro R.EXC, the geometry is slightly adapted for the area of use. The technical highlight of the full carbon bike is the rear triangle with the innovative Elevated Box Design. The Mid-High Pivot System is based on a higher and slightly forward pivot point and raises the bike's riding dynamics to a new level. The kinematics combine high symmetrical rear triangle stiffness with optimized anti-rise and anti-squat values.
