  1. THE STORY BEHIND THE RR340 MOUNTAIN BIKE
    This mountain bike was fully designed and developed at the B'Twin Village (Lille, France) and is the brainchild of an expert team of mountain bike enthusiasts. To give beginner mountain bikers the lightness and ease of use they need, the team got beginners involved at every stage of design, construction and testing for the RR340. Whether it's for riding alone, with friends or as a family, users have approved the RR340 as being really fun to ride!
  2. A UNISEX MOUNTAIN BIKE
    The RR340 mountain bike is designed for men and women alike. The RR340's frame has been carefully designed right down to the smallest detail, from the top tube's relatively pronounced slope, to the broad range of sizes (XS: 1.45m to XL: 1.95m) and the low weight to suit both men and women. To make the most of the improved comfort, the women of the Rockrider team recommend the 500 Women's Sport saddle that is adapted to women's morphology.
  3. HOW TO CHOOSE THE RIGHT SIZE RR340
    Several sizes available: XS: between 1.45m and 1.50m S: between 1.51m and 1.65m M: between 1.66m and 1.75m L: between 1.76m and 1.80m XL: between 1.81m and 1.95m Do you weigh more than 90kg? For your comfort and safety, "double-walled" rims (more durable) are a good idea. The Rockrider ST100 mountain bike will be even better for you.
  4. A LIGHT, EFFECTIVE FRAME
    To get the most out of your pedalling, the Rockrider 340's frame is made from 100% aluminium. Aluminium combines durability and a low weight. Its sloping geometry makes it easier for both women and men to mount.
  5. FRONT SUSPENSION FOR CUSHIONING LUMPS AND BUMPS
    The Suntour XCT 80mm front suspension is designed for slightly uneven trails and helps you overcome your first obstacles with no worries. Its design, based on a mechanical spring, is reliable and easy to maintain. You can also easily adjust the stiffness using a dial.
  6. REAR SUSPENSION: NONE
    This mountain bike has no rear suspension. It is a "semi-stiff" mountain bike: ideal for beginners. Compared with a full suspension bike (with rear suspension) the benefit is clear: it weighs much less so you waste less energy on flat terrain. A "semi-stiff" bike such as the RR340 is therefore a good choice for your first rides!
  7. DERAILLEUR & DRIVE TRAIN: CHANGE CHAINRING AND COG
    3 x 7 speed chainwheels, 21 speeds total!2 easy-to-use grip shifters on the handlebars.Left (chainrings): control ascents/descents. Right (speeds): more precise control over your pedalling. In detail: -Triple 22-, 32- and 42-tooth chainring + protection / grease -Shimano TZ30 or MICROSHIFT MS22 front derailleur -Shimano TY500 rear derailleur -SRAM MRX21 grip shifters with speed indicator -Shimano TZ21 7-cog, 14- to 28-tooth cassette -Wide, sturdy KMC Z51 chain
  8. STEM, HANDLEBAR, GRIPS: FOR GOOD HAND POSITIONING
    With a stem that tilts 10° upwards, the RR340 gives you a raised, accessible, comfortable riding position. In detail: 90mm (in sizes XS, S and M) or 110mm (in sizes L and XL) aluminium stem with an angle of 10° for maximum comfort - 620mm-wide steel handlebar, for stability and control -"Soft touch" grips for a firm yet soft and pleasant grasp
  9. SADDLE: SIT COMFORTABLY!
    Your comfort is our top priority, which is why we offer the exclusive, wider Ergofit saddle, with a special "hammock" shape. Easily adjust the height of your saddle with the 350mm-long, 29.8mm-diameter seat post.
  10. V-BRAKES: CONTROL YOUR BRAKING
    Brake effectively thanks to the V-brake brake pads.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels. Thanks to the special design of the RR340's aluminium brake levers, you only need two fingers to brake.
  11. 26" WHEELS & TYRES FOR DRY GROUND: READY TO ROLL?
    Push off easily on trails with your RR340 mountain bike and its light 26-inch single-walled wheels. To keep these wheels sturdy, our engineers have given them 36 spokes! Because your first rides will be on dry terrain, the DRY 26 x 2.0 tyres are the most suitable. Their performance has been optimised thanks to a faster central section, while their side lugs offer excellent traction in turns.
  12. FLAT PEDALS
    The Rockrider 340 mountain bike comes with flat mountain bike pedals made from hard resin for a lighter weight and greater safety. If your foot slips off the pedal, there's less risk of injury.
  13. EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE
    At ROCKRIDER, we know that not all rides start on your doorstep or right outside the store. You might need to transport or store your bike in a confined space (car boot, porch, etc.). To make it easier to mount / remove your front wheel, we've fitted it with a quick release system. There is a nut at the back to secure the bike and limit the risk of theft. You will need a spanner to remove the back wheel.
  14. WEIGHT
    14.5 kg in size XS without pedals. 14.8 kg in size S without pedals. 14.85 kg in M without pedals.15.0 kg in size L without pedals. 15.2 kg in size XL without pedals.
  15. ACCESSORIES
    Your BMX RR340 comes with a derailleur guard, chainwheel protection (to prevent dirt getting onto your clothes), bells, lights, wheel reflectors and pedals. The frame is compatible with: - Front and rear mudguards - Stand - Bottle cage - Saddle bag - Rear pannier rack - Child seat etc.
  16. COMFORT & SAFETY
    We recommend that beginners wear cycling shorts with a pad (foam in the shape of a saddle) or a gel saddle cover to reduce soreness. For longer rides, remember to take something to drink (e.g. a water bladder or bottle). In all circumstances, even for a short ride, wearing a helmet is essential!

  2. Storage advice

    Regularly maintain your fork (clean and grease dampers), especially in winter. Take your bike to your Decathlon store's customer service workshop, which offers a free safety inspection on all new bikes purchased.

  • Buckled wheel

    Used for 2 to 8 weeks
    Got this bike for my son for Christmas. First outing on it went off a kerb and the wheel buckled. I have never in my lifetime of cycling heard of a bike wheel buckling on a kerb. This is called a rock rider mountain bike but can’t even handle obstacles on a normal road. I will be contacting decathlon with regards to replacement wheels or a refund.
    Response of the brand
    I'm sorry to read that there was an issue with the wheel. This is the link to the customer team who will be able to assist you with a replacement, repair or a refund: https://www.decathlon.co.uk/en/contactUsWithoutAccount

    Many things can be wrong on a bicycle: from the brakes to the tyres but never in the history of humanity has it been seen that a bicycle does not turn either side.

    Today I was almost ran over by a car because I wanted to turn to another street but the handlebar was stiff. As a result of avoiding colliding with the cars in front I fell off the bike with the luck that no car passed behind.

    Men, women, children and families of the world, be cautious and do not buy this bicycle.

    Response of the brand
    Thank you for taking the time to post a review of your bike. It seems that the headset bearings have become stiff which means it may have seized up due to rust. This is easily and quickly remedied as headset bearings cost very little. As long as the bike is maintained and kept out of the rain when not in use, there should not be an issue. If this is the case then the workshop team will check this out with you to be sure.
    Please don't hesitate to contact your local Decathlon store workshop who can help with this.
    Regards
