UNISEX FRAME
A top tube with a relatively pronounced slope, over a wide range of sizes (S: 1.50m to XL: 2.00m),
The ST 120 mountain bike has a UNISEX frame.
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 LIGHTWEIGHT, COMFORTABLE, FUN FRAME
Our designers created a frame that's easy to get onto.
The 100% aluminium CGF frame (Comfort Geometry Frame) is both comfortable and easy to handle. The slope angle has been designed to keep your back straight, while the rear bases were shortened to make the bike very agile in turns.
DERAILLEUR & DRIVE TRAIN: A SINGLE CHAINRING LIKE THE PROS!
The single chainring is easy and efficient to use:
1 chainring and 9 speeds.
Accelerate on the flat and take on climbs with no compromise.
With a single lever on the handlebar, there's no need to even think!

-MICROSHIFT SL-759 right shifter

Front suspension
The 80 mm front suspension helps you overcome your first obstacles on slightly uneven trails with no worries.
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.
MECHANICAL DISC BRAKES
The Tektro TKD 68 160 mm double disc brakes provide powerful, progressive braking at the front and rear. The aluminium Tektro brake levers are precise, and easy to hold. Just two fingers are all you need to brake.
3 or 4 sets of 10 dry, intermittent stops are enough to break in your pads. 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 120 are tolerant and sturdy, with 19 mm double-walled rims with 28 spokes.
Slow down without worrying about obstacles: 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.
HANDLEBARS, STEM, GRIPS
With a stem that tilts 10° upwards, the riding position of the ST 120 is raised, accessible, and comfortable. In detail:
90mm aluminium stem with an angle of 10° for maximum comfort
- 640mm-wide steel handlebar, for stability and control
-"Soft touch" lamellar grips for a firm yet soft and pleasant grasp.
Saddle
The saddle of the ST 120 is welded to prevent any movement of the saddle.
And because your comfort is our priority after your 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.
Platform pedals
The Rockrider ST 120 mountain bike comes with resin mountain bike platform pedals for lower weight and increased safety.
If your foot slides on the pedal, there's less risk of injury.
TRANSPORT & STORAGE
We added a quick release system for easily attaching/removing the front wheel.
Our advice: a bike rack is an easy way to transport your mountain bike without dirtying your car.
Accessories
Your ST 120 mountain bike is supplied with a bell, lights, wheel reflectors and pedals.
