    1. THE STORY OF THE ROCKRIDER 540 S 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 540 S mountain bike with their mountain bike testers.
    2. A UNISEX MOUNTAIN BIKE
      Men's or women's mountain bike? The Rockrider 540 S 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: M: between 1.60 m and 1.75 m L: between 1.75m and 1.85m XL: between 1.85 m and 2 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 DESIGNED TO COMBINE FUN AND PERFORMANCE
      For lower weight, we designed the BTWIN SPORT frame in 6061 aluminium. The result: only 2.7 kg in size M (without shock). Its 120mm rear shocks rest on a monopivot system (more sensitive to small impacts on terrain, while remaining firm during large impacts) and on sealed bearings for a great lifespan.
    5. FRONT SHOCK FOR PRECISION AND CUSHIONING FROM IMPACT
      Easily surmount all obstacles (roots, pebbles, stones, etc.) with the SUNTOUR XCR hydraulic fork and its 120 mm travel. Steer a precise path with the higher diameter dampers (32 mm). Built into the right damper, its quick-release system helps prevent bobbing on smooth sections.
    6. REAR SUSPENSION: AIR SHOCK
      Our designers equipped the RR540 S with an X-Fusion E1 air shock, lightweight and specifically adjusted to this frame. You can easily adjust it based on your weight using the Schrader valve, which creates a very good balance between sensitivity and performance. A specific "high pressure" pump is required to adjust this shock (B'Twin fork and shock pump - ref: 3310286).
    7. DERAILLEUR & DRIVE TRAIN: REACH GREAT SPEEDS
      3 9-speed chainwheels, or a wide range of 27 speeds! 2 quick and easy shifters on the handlebar. Left (chainwheels): control ascents/descents. Right (speeds): more precise control over your pedalling In detail: - Triple chainwheels - 22, 32 and 42 teeth - SHIMANO ALTUS front derailleur - SHIMANO ALTUS rear derailleur - SHIMANO ALTUS M370 shifters, with speed indicators - SHIMANO HG 200 9-cog cassette, 11 to 34 teeth
    8. SADDLE / SEAT POST: COMFORTABLE AND SPORTY SEAT
      Our teams have designed the exclusive B'Twin Ergofit Evo saddle. Suitable for all hip sizes, its "hammock" shape is particularly good for sport touring. With a 31.6 mm diameter and 400 mm long, the aluminium B'TWIN SPORT seat post combines low weight and a wide range of adjustments for a more raised riding position. Adjust it easily with the ergonomic collar clamp.
    9. HANDLEBAR, STEM, GRIPS: TAKE CONTROL
      With its adjustable stem, the RR 540 S controls are close at hand. The all-aluminium B'Twin stem is 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 B'TWIN SPORT "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
    10. DOUBLE HYDRAULIC DISC BRAKES: GET A GRIP ON YOUR BRAKING
      No matter what conditions you ride in (dry/wet), the B'Twin by Tektro 160mm front and rear double hydraulic disc brakes will do the job, even in the mud. Hydraulic brakes are more powerful and progressive, requiring much less effort when applying pressure on the levers. The aluminium brake levers are easy to grip, lightweight, and precise.
    11. DOUBLE-WALLED 27.5" WHEELS
      Embark fearlessly on new adventures on trails with obstacles with the Aero Trail Evo wheels made of double-walled aluminium. Their 27.5" diameter is a perfect balance between comfort and performance, while their 28 spokes provide lightness, stiffness, and durability.
    12. ALL-TERRAIN TYRES
      The exclusive 27.5" x 2.2 B'TWIN ALL TERRAIN LIGHT tyres are lighter weight and have lugs that are specially designed for all-terrain rides. Their 2.2 width ensures more traction on technical sections.
    13. PLATFORM PEDALS
      The RR540 S comes with B'TWIN FLAT EVO resin pedals: both sturdy and lightweight. They are wider for more power when pedalling, and the studs are more prominent for a better grip on the pedal.
    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
      14.45 kg in M without pedals.14.55 kg in L without pedals. 14.65 kg in XL without pedals The weight can vary based on the tolerance of the components. The bike comes with B'Twin Flat Evo platform pedals. The total weight (bike + rider) should not exceed 120 kg.
    16. Accessories
      Your RR540 S mountain bike comes with a bell, lighting, wheel reflectors, and pedals. The frame is compatible with: - Mudguards attached to the diagonal tube on the frame and the seat post - Adjustable height seat post. - Stand - Bottle cage - Saddle bag - Rear pannier rack etc.

      Used for More than 2 years
      I purchased the bike 2 years ago when it was €318.
      I tried to put as much abuse as I could, just to see how far will it go.
      I mostly use it for commuting and occasional once a month off road.
      It held up great. I maintained it myself and still have all the original parts. The bike is on the heavier side but that was exactly what i was looking for.
      Sturdy and reliable.
