      Weight

      S: 15,1 kg
      M: 15.2 kg
      L: 15.3 kg
      XL: 15.5 kg

      Net weight without pedals

      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.

      Front suspension

      The 80 mm front suspension helps you overcome your first obstacles on slightly uneven trails with no worries.

      27.5" WHEELS & TYRES FOR DRY TERRAIN

      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.

      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!

      -ROCKRIDER FC ATB 100 - 32-tooth single chainring equipped with 2 chain guides (anti-derailment)
      -MICROSHIFT RD-M46-L rear derailleur
      -MICROSHIFT SL-759 right shifter
      -MICROSHIFT H092 9-cog cassette (11-36 teeth)
      -Wide, sturdy KMC Z9 chain

      MECHANICAL DISC BRAKES

      The Tektro 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.

      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.

      WHAT SIZE MOUNTAIN BIKE TO CHOOSE?

      Several sizes available:
      S: between 1.50m and 1.64m
      M: between 1.65m and 1.74m
      L: between 1.75m and 1.84m
      XL: between 1.85m and 2.00m
      To adapt the bike 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.
