Technical Information

A WORD FROM THE TEAM

Entirely designed and developed in France at the B'Twin Village (Lille).
The Rockrider team developed, designed and tested this XC 900 29" Mountain Bike by involving XC mountain bikers like our technical partner and professional racer, Milton Ramos, winner of different XC races all over the world.
To better meet your needs, the Rockrider XC 900 29 " is assembled just metres away from the design team, in our factory in Lille.

A UNISEX MOUNTAIN BIKE

Men's or women's mountain bike? This Rockrider XC 900 29" MTB is unisex.
For greater comfort, the women on our mountain bike team recommend replacing the saddle with the Women's 500 Sport saddle, which is adapted to women's bodies.
