    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.
    4. Rear suspension
      No rear suspension.
    5. Drivetrain
      Triple-chainring chainset (22/32/44 teeth). Shimano Altus 9-speed rear derailleur. Microshift MS25 front derailleur. Shimano Altus M370 shifters with speed indicators. Shimano HG200 cassette with 9 cogs and 11-34 teeth.
    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.
    7. Handlebar/stem/steering/grips
      B'Twin Sport Oversize aluminium handlebar; 660 mm (size S and M), and 680 mm (L and XL). Exclusive B'Twin aluminium stem, 70 mm (size S), 80 mm (sizes M/L), and 90 mm (size XL). Stem can be raised by up to 3 cm, with 5 settings (+ 0 mm, + 7.5 mm, + 15 mm, +22.5 mm, +30 mm). Semi-integrated A-headset headset—better sealed and integrated style. B'Twin Sport handles with grooves, 120 mm long: genuine comfort while riding.
    8. Wheels
      Aero Trail Evo aluminium wheels with double-walled rims: lightweight, stiff, and durable. 27.5" diameter: the best balance of comfort and performance. Designed with 28 spokes to reduce weight while still ensuring rigidity and strength.
    9. Tyres
      Exclusive B'Twin All Terrain Light 27.5" x 2.0 tyres with a system of lugs specially designed for all terrain use on any type of surface. Lighter tyre sidewalls reduce the effect of rotating mass. Chart with recommended tyre pressure based on rider's weight (indicated on the tyre sidewalls).
    10. Saddle / seat post
      Exclusive B'Twin Ergofit Evo saddle offers outstanding comfort thanks to its wider "hammock" shape and good distribution of pressure points regardless of the rider's pelvis width. B'Twin Sport seat post in aluminium for less weight. 27.2 mm diameter provides the seat with a natural flex that's 5 times greater than a classic seat post. 400 mm long, offering a broad adjustment range.
    11. Pedals
      Comes with B'Twin Flat Evo resin pedals: sturdy and lightweight. A large pressure surface area for more power while pedalling and improved directional control of your mountain bike. More aggressive pins for better contact between the foot and the pedal.

    • Awful product

      O'Reilly (United Kingdom)
      Used for 3 to 6 months
      Breaks do not work after 7 uses on both of the bikes and tyres keep going flat. Worst bike I have ever owned.
      Response of the brand

      Sorry to hear that you've had issues with your Rockrider 540. If you could give me some more details as to how the brakes do not work. As for the tyres, it could be something as simple as something in the tyre such as a thorn etc causing the air to escape., sometimes a small puncture can be very hard to detect with the naked eye so putting them in a water bath is useful to find the culprit (it could also be the valve itself)

      Kind regards

    • Xmas present

      Howard (United Kingdom)
      Used for 2 to 8 weeks
      I bought this bike for my 13 year old son for Xmas,went into the store a few times with him to make sure that was the bike he wanted.
      I have to say the customer service was by far the best I had ever received from any company,nothing was to much trouble for them.
      He had the bike around 2 weeks and I felt he needed the next frame size up,they changed it without any questions.
      The bike itself is great and very good quality for the money,I would recommend this bike and decathlon as a store to shop at
      Excellent customer service,no quibble exchanges
      No negatives
    • Rockrider 540 in XL

      martin (United Kingdom)
      Used for 2 to 8 weeks
      Had the bike about 4 or 5 weeks. I love it feels good brakes are good ride is very comfortable with wide handlebars and it looks good with the colour scheme! I do about 12 miles a day on it to and from work and the bottom bracket bearing has play in it already! This bike does not get abused nor have I fallen off it yet. It seems the case that cheap parts are used amongst expensive ones to keep the cost of the bike down and make more money on it!!
    • Nice spec, shame about the detail

      DAVID (United Kingdom)
      Used for 1 week or less
      I bought this bike just starting out in MTB and really looking forward to it. 7 months in and I am incredibly disappointed. I've used the bike regularly and had nothing but problems with the both the gears which stick and the brakes that don't work. The spec on this is great and it looks nice but it's obvious that to keep the cost down Btwin cut corners with cheap components. My wife got a bike for about the same price from Halfords and has had zero problems and she loves it. I maintain both bikes. I've contacted Decathlon previously about this and had no response so felt compelled to leave this review. Also, they don't give you any information on the 12 week safety check up they promise. All in all a bad experience and I won't be buying anything like this again from Decathlon. It was, until recently, my favourite store.
      Good spec and looks ace.
      Obvious cut corners on brakes, gears etc.
      Response of the brand
      Hello David,

      Sorry to hear about the problems you are still facing with this bike. The 12 week service, you receive an e-mail informing you of when it is due, this will only happen if you scanned your decathlon card on buying the bike. Anywhere between 3-6 months is normally accepted by stores when it comes to having your service done.

      In terms of having the bike fixed you will be best to speak with your local store to see when they are available to have a look at the bike for you.
