Progressive kinematics for best ride comfort

 

The kinematics of our frames have been studied in order to offer our riders a progressive, comfortable and efficient bike.

For optimal running of our Stellar 27.5, we recommend a linear shock (high volume air or spring).

 

The geometry of the Madnes Stellar 27.5 has been designed to adapt to current standards while maintaining the pleasure and tolerance of an enduro mountain bike

Débattement : 230x57.5 = 160mm / 230x60 = 165mm / 230x62.5 = 170mm
