    1. THE STORY OF THE ROCKRIDER 520 MOUNTAIN BIKE...
      Entirely designed and developed in France at the B'Twin Village (Lille), this mountain bike is the fruit of the work of an expert team of passionate mountain bikers. The Rockrider team designed and tested the Rockrider 520 mountain bike with their test riders.
    2. A UNISEX MOUNTAIN BIKE
      Men's or women's mountain bike? The Rockrider 520 mountain bike is unisex. For greater comfort, the women on our mountain bike team recommend replacing the saddle with the Women's 500 Sport saddle, which is adapted to women's bodies.
    3. HOW DO I CHOOSE MY MTB SIZE?
      Several sizes available: S: between 1.50m and 1.64m M: between 1.65m and 1.74m L: between 1.75m and 1.84m XL: between 1.85 m and 2.00 m If you are on the limit between 2 sizes: Choose the smaller size for easier steering (easier to handle) and comfort (straighter back). Choose the larger size for easier pedalling with a more stretched-out position (position more suited to performance).
    4. A FRAME THAT COMBINES THE JOY OF THE RIDE & THE PLEASURE OF STEERING
      For a lighter weight and more efficient pedalling, the Rockrider 520 frame has been designed with 6061 aluminium (only 1.9 kg in size M). The lower bottom bracket helps keep you more stable during turns.
    5. FRONT SUSPENSION TO CUSHION UNPREDICTABLE TERRAIN
      Calmly face new obstacles (roots, pebbles, stones, etc.) with the front fork with 80 mm of travel. Easy: use the wheel to adjust the stiffness of the fork based on your weight.
    6. REAR SUSPENSION: NONE
      This mountain bike has no rear suspension. This is a "semi-rigid" mountain bike. Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: lighter weight, you will spend less energy on flat ground. However, if you want more comfort, the RR 520 also exists in a "full suspension" version with a rear shock absorber.
    7. DERAILLEUR & DRIVE TRAIN: REACH GREAT SPEEDS
      3 8-speed chainwheels, or a wide range of 24 speeds. 2 quick shifters on the handlebar. Left (chainrings): control ascents/descents. Right (speeds): more precise control over your pedalling. In detail: - Triple chainwheels - 22, 32 and 42 teeth - MICROSHIFT MS22 front derailleur - SRAM X3 rear derailleur - SRAM X4 shifters, with speed indicators - SRAM PG820 8 cog cassette, 11 to 32 teeth
    8. SADDLE / SEAT POST: COMFORTABLE AND SPORTY SEAT
      Since your mountain bike rides will get longer and longer, it is important to have a suitable seat. So our teams have designed the exclusive B'Twin Ergofit Evo saddle. Suitable for all hip sizes, its "hammock" shape is particularly noticeable during sport touring. Along with the 27.2 mm diameter aluminium FLEX seat post, it guarantees greater comfort. Easily adjust the seat height using the quick release on the seat clamp.
    9. DOUBLE DISC BRAKES: GET A GRIP ON YOUR BRAKING
      No matter what conditions you ride in (dry/wet/mud), the HAYES MX5 front and rear mechanical disc brake calipers offer powerful, progressive braking. The TEKTRO aluminium brake levers are easy to grip, lightweight, and precise.
    10. DOUBLE-WALLED 27.5" WHEELS
      Have fun with the 27.5" double-walled aluminium Aero Trail Evo wheels. Their diameter is the perfect balance between comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.
    11. TYRES FOR DRY TERRAIN
      The exclusive 27.5" x 2.0 B'TWIN ALL TERRAIN DRY tyres are adapted to dry ground. Their side lugs provide good traction during turns. The central tread provides good performance and the side lugs offer traction during turns. Recommendations for pressure based on the cyclist's weight are marked on the sidewalls.
    12. PLATFORM PEDALS
      The RR 520 comes with MTB bearing-mounted platform pedals made of hard resin for light weight and safety. If your foot slips off the pedal, there's less risk of injury.
    13. Weight
      14.35 kg in S without pedals. 14.45 kg in M without pedals. 14.55 kg in L without pedals. 14.70 kg in XL without pedals. The weight can vary based on the tolerance of the components. The bike comes with B'Twin platform pedals. The total weight (bike + rider) should not exceed 120 kg.
    14. Accessoires
      Your RR520 mountain bike comes with a bell, lighting, wheel reflectors, and pedals. The frame is compatible with: - front and rear mudguards, - stand, - bottle cage, - saddle bag, - rear pannier rack, - child seat (add an additional pannier rack for sizes S and M to avoid touching the rear wheel) etc.
    15. OUR ADVICE FOR YOUR FIRST RIDE
      Tip No.1 When mountain biking, there is always the risk of a fall: don't forget to wear a helmet. Tip No.2 Even if the saddle is comfortable, cycling shorts with a pad (saddle-shaped foam) are a real plus for preventing glute pain. Tip No.3 If you don't want to stop to drink, bring water in a bottle or water bladder to access it while riding. Tip No.4 Punctures are always possible, remember to bring a repair kit.
    16. Accessoires
      Votre VTT RR520 est livré avec sonnette, éclairages, catadioptres de roues (réflecteurs) et pédales. Le cadre est compatible avec : - gardes-boues avant et arrière, - béquille, - porte bidon, - sacoche de selle, - porte bagage arrière, - siège enfant (prévoyez un porte-bagage en plus pour la taille S et M pour ne pas toucher la roue arrière) ...
    17. NOS CONSEILS POUR LA PREMIÈRE SORTIE
      Conseil n°1 En VTT, nous ne sommes jamais à l'abri d'une chute: n'oubliez pas de porter un casque. Conseil n°2 Même si la selle est confortable, le cuissard avec une peau (mousse en forme de selle) est un vrai plus pour atténuer les douleurs aux fesses. Conseil n°3 Si vous n'avez pas envie de vous arrêter pour boire, pensez à emporter de l'eau dans un bidon ou un sac à eau pour y accéder tout en roulant. Conseil n°4 Une crevaison peut toujours arriver, pensez à emporter un kit de réparation

      Used for 7 to 12 months
      I've had the bike almost a year and have looked after it. I use it to commute and for leisure. I've had little issues with it, it's a smooth runner and can handle well. I've been off road with it too and I never experienced any discomfort. However sometimes during gear changes the chain can lock up meaning I have to pull over or go back to the gear I was in before it happened to try and correct it. However this has only happened about 3 or 4 times in the last 10 months. Everything else is great!
