    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.
    12. Weight
      13.50 kg in S without pedals. 13.95 kg in M without pedals. 14.05 kg in L without pedals. 14.20 kg in XL without pedals.
    13. Accessories
      Frame can take a bottle cage, saddle bag, mud guard, stand, pannier rack.
      Cycle touring does not start from home; that's why we have made it easier to remove and replace the front and rear wheels. They are equipped with a quick-release system.

      13.50 kg in S without pedals. 13.95 kg in M without pedals. 14.05 kg in L without pedals. 14.20 kg in XL without pedals. The weight can vary based on the tolerance of the components. The bike comes with B'Twin Flat platform pedals. The total weight (bike + rider) should not exceed 120 kg.

    • Good bike

      Brett (United Kingdom)
      Used for 2 to 8 weeks
      Note that if you buy online and collect in store you get no instruction/maintenance manual nor any tools. No details on either the three month safety check or the online registration are provided neither.
    • Love it

      PJ (United Kingdom)
      Used for 2 to 8 weeks
      Great entry into the mountain bike world, and for beginners/improvers it's a solid choice. Handles downhill trails with relative ease, and not too laboured for uphill/touring.
    • Poor Components

      Neil (United Kingdom)
      Used for 7 to 12 months
      I purchased this bike for my son last July as i have been very very happy with Decathlon bikes over the years. Unfortunately this now not the case. Since having the bike it has been taken back 6 times. It has has had 2 new rear cassette's 3-4 chains and problems with the crank. It was last taken in to store at the end of February with more gearing issues. As of today 28/4/2018 it has malfunctioned again. Would now think long and hard before buying from decathlon again. I am now waiting to hear from customer service team as i have requested a refund.
      Response of the brand
      Dear Sir,
      I'm very sorry to read that you have had so many issues with your bike. 2 cassettes (3 in total) and 4 chains (5 in total) over 9 months really is excessive. I can assure you that we use parts commonly found on many bikes (shimano cassette and KMC chain) therefore I am at a loss to explain why this is happening to your bike. Chains for example can last thousands of miles if cared for. Your local Decathlon store and workshop can help fully identify the cause of a fault and ensure that you are satisfied. Could you kindly give me the name of your local store.
      I look forward to hearing from you.
