    Product feature
    1. Design
      The ROCKRIDER 540 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:
    2. 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.
    3. Front suspension
      Suntour XCR 100 fork with 100 mm of travel and adjustable stiffness (more/less). Fork lockout to prevent bobbing on faster terrain.

    6. Brakes
      Hayes Radar hydraulic disc brakes on the front and rear, with 160 mm discs. OR B'Twin by Tektro hydraulic disc brakes on the front and rear, with 160 mm discs. Hydraulic brakes are more powerful and gradual, requiring much less effort to be applied to the levers.

      Bought this bike for my wife. Great spec for the price and feels reasonably capable. Just needs to go in for a breaking in service!
    • Best bike ive had so far but...

      christopher (United Kingdom)
      Used for 1 week or less
      This bike is the best Ive had the brakes are superb and so are the gears.
      The one thing I'm not happy about it the fact that the rear brake leaver snapped in half when it fell over yet it shouldn't have and I have had this bike 4 days but that's the only downside but I think it must be a fault in the metal work for this to happen.
