Great bike, poor tyres

Really like this bike. Spent a long time searching for something suitable and I’m glad I decided to go with this one. All mechanics work as they should and are fit for purpose. The only downside is the tyres appear to be of very poor quality. Out of the 6 rides I have been on since my purchase, I have picked up a puncture on 3 of them! I have been on each ride with my brother on his Giant mountain bike which has somehow avoided all of the puncture traps which I must have hit. I have ridden mountain bikes off road for years but have never experienced such frequent puncturing. Would recommend the bike but definitely worth getting some different tyres for it.

Excellent for the price range

Comfortable easy ride bike. Very light. Good brakes. 9 gears are more than enough for me. Definitely will recommend.

Excellent bike

I love the ride of this bike! I’m so glad to found this bike at Decathlon!

Велосипеда е добър и напълно приемлив за съотношението качество/цена. При вземане на решението за покупката роля изигра и факта,че Декатлон разполагат със вело сервиз,който осигурява безпроблемно обслужване в гаранционен срок,а и след това.

Велосипеда е добър за мен бързо превключва скоростите и са напълно достатъчни въпреки единия венец от пред, спирачките са плавни и спират отлично, като недостатък ми се струва, че е малко тежичък. Моля да напишете в описанието реалните му килограми, за да може да се изпълни вашата препоръка 120кг максимално натоварване на каращия заедно с велосипеда, но колко е велосипеда никой не знае.


Хидравликата не отговаря много добре

Най-доброто обслужване

Много леко се кара. Мнага е леко здраво добре изглежда. Удоволствие е да се кара. За сега няма някакви проблеми и се надявам да няма.

Doporučuji, cena výkon je super

Jednoduché kolo, bez zbytečných součástek za naprosto lidovou cenu. Pokud hledáte levné kolo určené i do těžšího terénu, nešlápnete vedle. Nejedná se o sjezdové kolo! Ale s nezpevněným povrchem si poradí velmi dobře. Mám ho už dva roky a zatím jezdí, funguje jak má, stačí obyčejná údržba a servis opotřebovaných součástek tak jako na jiných kolech (střed, pneu, destičky aj.). Za tu cenu získáte fajnové kolo pro vaše projížďky - dokonce i na lehčích trailech, jako například jsem s ním projel KOKO stezky -

Additional Product informations



  • 100% Aluminium 6061

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 1.85 m and 2.00 mIf you are 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).

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 530 mountain bike frame is UNISEX.The ST 530 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 530 mountain bike was fully designed and developed by our passionate MTB team at the B'Twin Village in France (Lille).A mountain bike that makes steering easier: more powerful and progressive hydraulic disc brakes, a fork with 100 mm travel for riding over obstacles, a single chainring so you can very quickly adapt to changes in terrain, etc. MTB riders were involved at every stage of this bike's creation to make sure it works just right.

A light, comfortable frame

For less weight and more efficient pedalling, the Rockrider ST 530 frame is made from 6061 aluminium (only 2.1 kg in size M). Our designers created this bike to be comfortable and easy to manoeuvre. Its slope was carefully designed to keep your back straighter. The lower bottom bracket helps keep you more stable during turns.

100 mm front suspension

With a 100 mm front suspension, it will be easier to ride over small obstacles (roots, pebbles, stones, mud).Easily adjust the hardness using U-Fit technology (weight adjuster). Simply set the number to your weight (55 kg to 105 kg) using the dial on the fork.

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: the mountain bike is lighter; less energy is lost on flatter ground. If however your primary concern is comfort and manoeuvrability, the ST 530 is available in a full suspension version with suspension at the rear.

Derailleur & drivetrain: a single chainring like the pros!

The single chainring is easy and efficient to use:1 chainring and 9 speeds.Accelerate on the flats and easily tackle the climbs.With a single lever on the handlebar, you can change gears while hardly thinking!-ROCKRIDER FC ATB 500 32-tooth single chainring-MICROSHIFT ADVENT rear derailleur with long cage-MICROSHIFT ADVENT right shifter-MICROSHIFT H092 9-speed cassette (11-42 teeth)-KMC Z9 wide, sturdy chain

Handlebars, stem, grips

The adjustable stem brings the ST 530 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:- 720mm oversize ROCKRIDER SPORT aluminium handlebar- ROCKRIDER SPORT "soft touch" ergonomic grips for good grip and a comfortable feel.


The ST 530 saddle is welded to prevent any saddle movement as you cycle.Because your comfort is our next priority after safety, we've added an exclusive Rockrider Ergofit Evo saddle that is wider and hammock shaped.Easily adjust the height of your saddle with the 400 mm Flex steel seat post. Its smaller 27.2mm diameter provides your seat with natural flexibility, 30% more than a standard solution.

Hydraulic disc brakes

No matter what conditions you ride in (dry/wet), the Rockrider by Tektro 160mm double hydraulic disc brakes will come through for you, even in the mud.Hydraulic braking adds more power and progressive braking and requires less powerful use of the brake levers.The aluminium brake levers are easy to grip and precise.

27.5" wheels with double-walled rims and all-condition tyres

The aluminium wheels are effective and sturdy: 27.5" diameter and double-walled rims. Their diameter is the perfect balance of comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.The wide, ROCKRIDER ALL CONDITIONS (30 TPI) 27.5" x 2.0 tyres have side knobs designed for riding on all types of terrain (dry, wet, etc.).Tubeless Ready 23 mm rims: SCHRADER valves, TUBELESS rim tape, TUBELESS tyres, and puncture-proof liquid to be added.

Platform pedals

The ST 530 comes with Rockrider Flat platform pedals with a wider pedalling surface and more pronounced dots for better grip on the pedal.

Easily transport and store your mountain bike

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.
