Product feature
  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 - SHIMANO Altus or MICROSHIFT MS22 front derailleur - SRAM X3 rear derailleur - SRAM X4 shifters, with speed indicators - SRAM PG820 8 cog cassette, 11 to 32 teeth
  8. HANDLEBAR, STEM, GRIPS: TAKE CONTROL OF THE HANDLEBARS
    With its adjustable stem, the RR 520 controls are close at hand. The all-aluminium B'Twin stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised using 5 adjustment intervals: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm. In detail: - Aluminium "oversize" handlebars are 660 mm (size S and M) or 680 mm (for L and XL) wide - B'TWIN SPORT "soft touch" grips for a good grip and comfortable feel in your hands.
  9. 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.
  10. 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.
  11. 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.
  12. 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.
  13. 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.
  14. EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE
    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.
  15. 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.
  16. Accessories
    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.
  17. 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.

  • Good bike but...

    18/10/2018
    Chris (United Kingdom)
    Used for 2 to 8 weeks
    I liked the bike, it seemed like it was ideal. I had to order it into the store which took a few days, not a big problem. When I went to pick the bike up the derailer was not working. One of the bike techs tried to fix it with small adjustments but failed. They said that they would need to replace the derailer and it work take 30mins. I pick the bike up 2 days later and it seemed fine. When I was at home the derailer, which was not proper tightened, spun and jammed the chain. I had to realign and properly tighten the derailer and make further adjustments to the brakes. Disappointing.
