This 27.5" MTB is designed for mountain bike rides lasting 2 to 3 hours, any time of year.

With your ST 530 you can accelerate and brake very quickly to adapt to changes in the terrain! The single chainring and hydraulic disc brakes will boost your mountain bike touring rides.

Cycling comfort: Enjoy the raised position, adjustable stem, 100 mm suspension and hammock saddle.

Ease of use: Change gears effortlessly: 9-speed single chainring drivetrain.

Directional control: Control your trajectory: hydraulic disc brakes, wide tyres and handlebar.

Efficiency: Smooth riding: lightweight aluminium frame, single chainring, 27.5" wheels.

CHOOSING YOUR MTB SIZE: Several sizes available:.

S: 1.50m to 1.64m.

M: 1.65m to 1.74m.

L: 1.75m to 1.84m.

XL: 1.85m to 2.00m. If you are on the cusp between 2 sizes:. Choose the smaller size for easier steering (easier to handle) and comfort (straighter back).

Choose the larger size for more powerful pedalling with a more stretched-out position (more suited to performance).

UNISEX FRAME: With a heavily sloped top tube and a wide range of sizes (from S: 1.50m 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. If as a WOMAN 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 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), it has the following advantages: the bike is lighter; you can pedal faster on flatter ground.

If however your primary concern is comfort and steering, the ST 530 is available in a full suspension version with suspension at the rear.

DERAILLEUR & DRIVETRAIN: A SINGLE CHAINRING, JUST LIKE THE PROS!: Enjoy the ease and efficiency of a single chainring. 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 effortlessly! 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 HANDLEBAR, STEM, GRIPS: The adjustable stem on the ST 530 allows you to position the levers so they're easy to grip.

The all-aluminium ROCKRIDER stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised in 5 adjustment intervals: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm. In detail:. 720 mm oversize ROCKRIDER SPORT aluminium handlebar.

ROCKRIDER SPORT "soft touch" ergonomic grips for good grip and a comfortable feel SADDLE: The ST 530 saddle is welded to prevent any saddle movement as you cycle. Because your comfort is our top priority after your 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 reduced diameter (27.2 mm) 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 160 mm double hydraulic disc brakes will come through for you, even in the mud. Hydraulic brakes deliver more powerful and progressive braking and require less effort applied to the brake levers.

The aluminium brake levers are light, 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 28 spokes, they are lightweight, stiff, and durable. The wide, exclusive 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: you will need rim tape, Schrader valves, and puncture sealant.

PLATFORM PEDALS: The ST 530 comes with Rockrider Flat platform pedals with a wider surface and more pronounced dots to better keep your foot on pedal.

TRANSPORT AND STORE YOUR MOUNTAIN BIKE EASILY: We added a quick release system for easily removing/reattaching the front wheel.
