    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

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.

      Good bike but compression in brakes may need updating every now and again or get done on warranty
    • Poor bike & poor customer service

      Thomas (United Kingdom)
      Used for 2 to 8 weeks
      I bought this bike in late August to for my wife just before going on holiday to France.
      The chain started coming off (multiple times) from day one. The chainrings would also not change, and my wife is forced to use the largest one only now.
      I am not at all impressed with the quality of the bike.
      To make matters worse, when I contacted Decathlon's customer loyalty team when we got back from holiday, they said that "unfortunately, the wear and tear are not included in the warranty". The bike is literally new and was hardly used, because it was faulty.
      Not happy.
      Response of the brand
      I'm sorry to read that you seem to have been given the incorrect information. Cables do stretch a little and it is possible for gearing to require some adjustment but it may also be that the bike was not set up well enough to begin with which is not satisfactory. This needs to be resolved (which is a quick process).
      I will ask the customer team to contact you again regarding this matter.

    • Cheap Brakes

      james (United Kingdom)
      Used for 7 to 12 months
      Bike seems to be well built but the hydraulic brakes are not the best, I purchased the bike 7 months ago and at first the brakes weren't great but having never used a bike with hydraulic brakes before i pressumed it was the way they were. After the first 4 months the brakes seem to stop working having only used the bike a handful of times and covering 50 miles. When i manage to take it back to decathlon they told me that the brakes need bleeding which costs 40 pound and recommended that i had a new set of pads on the front. i refuse to pay out that much on a bike thats only cover 50 miles of canal riding, so now the bike is currently sitting in the shed not being used. As the brakes weren't the best from day one i assume that they would of needed bleeding before i bought the bike.
