Technical Information

Design
The ROCKRIDER 540 was designed and created in Suzhou, China, by a team of experts and cycling enthusiasts dedicated to designing our mountain bike Sport Touring line. Production was also done near Suzhou, as close to our Decathlon stores as possible.

Frame
Rockrider CGF Evo (Comfort Geometry Frame) 6061 aluminium frame for 27.5" wheels. Comfortable seating position thanks to raised steering. Seat is 5 times more flexible than a standard frame thanks to a narrow 27.2 mm seat post. Low bottom bracket: helps keep the mountain bike stable in turns, and makes it easier to place foot on the ground. Open steering angle (69.5°): keeps mountain bike stable while riding. Short rear wheel base: bike is easy to turn. LIFETIME WARRANTY!
