A LIGHTWEIGHT, COMFORTABLE, FUN FRAME
Our designers created a frame that's easy to get onto.
The 100% aluminum 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 8 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
-MICROSHIFT H081 8-cog cassette (11-34 teeth)

FRONT SUSPENSION
The 80 mm front suspension allows you to overcome your first obstacles with peace of mind on slightly uneven trails.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.
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 the first hikes are on dry ground, the DRY 27.5 x 2.0 tires are the most suitable. Their performance is optimized thanks to a very rolling central part, while their side studs provide good grip in turns.
MECHANICAL DISC BRAKES
The Tektro TKD 68 160 mm double disc brakes provide powerful, progressive braking at the front and rear. As for the 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.
Remember to have your disc brakes serviced once a year.
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 350 mm or 400 mm long (according to the bike size). Its reduced diameter of 27.2 mm gives your seat a degree of flexibility that is 30% greater than a conventional solution.
Sold flat pedals
The Rockrider ST 120 mountain bike comes with resin mountain bike platform pedals for lower weight and increased safety.
If your foot slips off the pedal, you will be less likely to injure yourself.
TRANSPORT and STORAGE
We added a quick release system for easily attaching/removing the front wheel.
Our advice: a bike carrier is a simple way to transport your mountain bike easily, without dirtying your car.
