    1. Design
      The ROCKRIDER 340 was designed and created in France, at the B'Twin Village in Lille, by a team of experts and cycling enthusiasts dedicated to designing our mountain bike Sport Touring line. Production took place in different factories in Europe as close to our Decathlon stores as possible. More information available on our website:

    3. Front suspension
      Suntour XCT front suspension with 80 mm travel and stiffness adjustment dial. Equipped with a mechanical spring and elastomer stoppers for maximum reliability and minimum maintenance.

Aluminium stem, 90 mm (XS / S / M) or 110 mm (L / XL), with a 10° angle for maximum comfort. Aheadset-type headset for greater shock resistance and more stiffness in turns. B'Twin Sport 100 grips have a soft-touch finish for better grip and extend the grip shifters.

      Inexpensive bike and you get what you pay for. I was initially happy but then the gears became a bit cranky and now the headset bearings are damaged. However, the bike is okay for that price.

      Casse-cou s’abstenir, ce vélo est parfait pour se remettre en jambe mais ne support pas trop les contraintes. Cependant c’est un très bon rapport qualité/prix
