Mountain bike

Good bike, very easy to put together (minimal build required) only just started to use it due to better weather, too early to tell if it stands the test of time, but so far so good.

Great value for money

Although I haven't had the bike for long, I've been very impressed so far. The spec offers great value for money and (touch wood) have had no problem keeping up with the kids on trails.

Great bike

Well...people bitch about cheap bikes....But sometimes you don't get what you pay for! I looked for a mtb that did not cost to much but was worth buying and came across this bike. I have to say it is well made....looks great and worth every penny. It looks amazing but the stickers on the forks and wheels are not for me and the reflectors in the wheels so i removed them and now the bike looks less bling! It rides great and feels great. Well worth the money.

Great bike for the money

Additional Product informations

Composition

Frame

  • 100% Aluminium

Which is the right size?

Several sizes available:S: between 1.50m and 1.64mM: between 1.65m and 1.74mL: between 1.75m and 1.84mXL: between 1.85m and 2.00mTo adapt the MTB to your height and size, try these tips:1/ Sitting on the saddle, you should be able to touch the ground with the tips of your toes.2/ To adjust the saddle height, your knee should be slightly flexed with the foot on the pedal in the lowest position.3/ If you're between two sizes, choose the larger size.

Unisex frame

With a heavily sloped top tube and a wide range of sizes (from S: 1.50 m to XL: 2.00 m).The ST 520 mountain bike frame is UNISEX.The ST 520 mountain bike is available with the same frame in a WOMEN'S version: fitted seat, narrower handlebar, shorter stem, fork with a more flexible spring, and brake levers that are closer together.As a WOMAN, if you choose the MEN'S model, we recommend at least purchasing the WOMEN'S SPORT 500 saddle which is fitted to the female form.

A word from the team

The ST 520 mountain bike was fully designed and developed by our passionate MTB team at the B'Twin Village in France (Lille).Mountain bikers we talked to expressed their need for control so they can take more risks and continue to improve their technical skills. With that as a starting point, we designed and tested the ST 520 mountain bike, involving MTB riders at every stage.

A light, comfortable frame

Our designers created a frame that's easy to get onto.The CGF frame (Comfort Geometry Frame) EVO is made of 100% aluminium for greater comfort. Its slope was carefully designed to keep your back straighter.

Front suspension

The 80 mm front suspension helps you get started with overcoming obstacles on slightly uneven trails easily.Easily adjust the hardness using U-Fit technology (weight adjuster). Simply set the number to your weight using the dial on the fork.

Rear suspension: none

This mountain bike has no rear suspension.It is a "semi-stiff" mountain bike: perfect for beginners launching themselves into their first mountain bike touring rides.Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: the mountain bike is lighter; you spend less energy on flat ground.

Derailleur & drivetrain:

3 x 8 speeds, 24 speeds total!2 shifters on the handlebar.Left (chainrings): control ascents/descents.Right (speeds): more precise control over your pedalling.In detail:-22, 32 and 42 T triple chainring + guard-SHIMANO ALTUS front derailleur-MICROSHIFT RD-M46-L rear derailleur-MICROSHIFT TS39 shifters-SHIMANO 8-speed cassette (11/32 T)-KMC Z7 wide, sturdy chain

Handlebars, stem, grips

The adjustable stem brings the ST 520 controls to your hands. The all-aluminium ROCKRIDER stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised to 5 adjustment intervals: + 0mm, + 7.5mm, + 15mm, + 22.5mm, + 30mm.In detail:- 680mm oversize ROCKRIDER SPORT aluminium handlebar- ROCKRIDER SPORT "soft touch" ergonomic grips for good grip and a comfortable feel.

Saddle

The ST 520's saddle fixing (welded) prevents any saddle movement as you cycle.Because your comfort is our next priority after safety, we've added an exclusive wider Ergofit saddle with a hammock shape.Easily adjust the height of your saddle with the Flex steel seat post, either 350mm or 400mm long (according to the bike size). Its reduced diameter of 27.2mm provides your seat with natural flexibility, 30% more than a standard solution.

Mechanical disc brakes

The Hayes MX or Tektro TKD 68, 160 mm double disc brakes provide powerful, progressive braking at the front and rear. The aluminium Tektro brake levers are light, precise, and easy to hold. You can brake with just two fingers.Try to get your brakes adjusted at least once a year.

27.5" wheels & tyres for dry terrain

The 27.5" wheels of the ST 520 are tolerant and sturdy, with 19 mm double-walled rims with 28 spokes. Overcome your first obstacles without fear: small rocks, cracks, holes and bumps!Because your first tours will be on dry ground, the Dry 27.5 x 2.0 tyres are most suitable. Their performance is optimised thanks to the rounded central section, whilst the side lugs provide good grip on turns.

Platform pedals

The Rockrider ST 520 mountain bike comes with flat mountain bike pedals made from hard resin for lighter weight and greater safety.If your feet can slide off the pedals when needed, there's less risk of injury.The pedals on the ST 520 are compatible with toe clips.

Transport & storage

We added a quick release system for easily removing/reattaching the front wheel.Our advice: a bike rack is an easy way to transport your mountain bike without dirtying your car.

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 seatetc.

Comfort & safety

Your bike's fittings (chain, derailleur, brakes, etc.) will adjust over time. Take advantage of a free servicing within 6 months after purchase. Our technicians will carry out a 13-point check of your bike. Just come to your nearest Decathlon workshop with your Decathlon card and/or receipt.

Legal disclaimer

To ensure components last longer, we recommend a maximum load of 120 kg (rider and MTB included).
