  1. WHAT OUR TEAM HAS TO SAY
    This ST 520 mountain bike has been entirely designed and developed at the B'Twin Village in France (Lillle). We've designed, developed and tested the ST 520 MTB for comfort and efficiency. This combines to give MTBers confidence to overcome any new obstacle. We have involved real MTBers at every stage of this bike's design process. And we hope that the Rockrider ST 520 is everything you could hope for to give you excellent MTB rides.
  2. A UNISEX MOUNTAIN BIKE
    Men's or women's mountain bike? This Rockrider ST 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. A range of Rockrider mountain bikes specifically designed to fit female morphology is also available (specialised saddle, stem, fork and brake grips).
  3. HOW TO CHOOSE YOUR ST 520 MOUNTAIN BIKE 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 COMFORTABLE, PLAYFUL FRAME
    For a lighter weight and more efficient pedalling, the Rockrider ST 520 frame has been designed with 6061 aluminium (only 1.9 kg in size M). Our designers have designed and developed it so it is comfortable and easy to manoeuvre. Its slope has been designed to keep your back straighter. The lower bottom bracket helps keep you more stable during turns.
  5. FRONT SUSPENSION TO CUSHION UNPREDICTABLE TERRAIN
    Directly adjust the stiffness of the suspension to your weight, to more easily travel over roots and stones. The 80 mm front suspension is designed for slightly uneven trails and helps you overcome your obstacles with no worries. It is based on a mechanical spring and is reliable. And it's easy to look after.
  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 ST 520 MTB also exists in a "full suspension" version with a rear shock absorber.
  7. DERAILLEUR & DRIVE TRAIN: HOW TO CHANGE SPEEDS
    3 8-speed chainwheels, or a wide range of 24 speeds. 2 quick 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 or MICROSHIFT FD-M22 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 ST 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: + 0mm, + 7.5mm, + 15mm, + 22.5mm, + 30mm. In detail: - 680mm oversized aluminium handlebars - Soft touch B'Twin sport grips for good grip and a comfortable feel.
  9. SADDLE / SEAT POST: COMFORTABLE AND SPORTY SEAT
    Our teams conceived and designed an exclusive saddle for this bike. Suitable for different hip sizes, its "hammock" shape is particularly good for sport touring. The Flex 27.2mm diameter aluminium seatpost also contributes to its increased level of comfort. Quick and easy tool-free adjustment of your saddle height using the adjustment lever on the seat post clamp.
  10. MECHANICAL DISC BRAKES: GET A GRIP ON YOUR BRAKING
    The HAYES M-X5 mechanical double disc brakes give you gradual, powerful braking at the front and back. Whilst the aluminium Tektro brake levers are light, precise, and easy to hold. Just two fingers are all you need to brake. Try to get your brakes adjusted at least once a year.
  11. 27.5" DOUBLE-WALLED WHEELS & TYRES FOR DRY GROUND
    Take on obstacles! The aluminium wheels are effective and sturdy: 27.5" double-walled rims. Their diameter is the perfect balance between comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.The exclusive 27.5" x 2.0 B'TWIN ALL TERRAIN DRY tyres are designed for dry terrain. Their side lugs provide good traction during turns. The recommended tyre pressure according to the weight of the rider is marked on the tyre sidewall.
  12. PLATFORM PEDALS
    The ST 520 is supplied with platform MTB pedals mounted on bearings, made from resin for light weight and safety. If your foot slides on the pedal, there's less risk of injury.
  13. EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE
    Not all rides start on your doorstep. Need to remove the front wheel? It's easy thanks to the integrated clamping lever. And the rear wheel? There is a nut at the back to secure the bike and limit the risk of theft. A flat spanner is needed to remove the rear wheel. A bike carrier will make your life easier if you want to avoid dirtying your car.
  14. ACCESSORIES
    Your ST 520 mountain bike is supplied with a bell, lights, 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 FEW RIDES
