      Product information

      Designed for your first bike rides.

      WEIGHT

      S: 15,1 Kg M: 15,2 Kg L: 15,3 Kg XL: 15,5 Kg Net weight without pedals

      LIGHTWEIGHT, COMFORTABLE AND PLAYFUL FRAME

      Our designers have designed a brand-new, easy-to-step-over frame. This 100% aluminum CGF (Comfort Geometry Frame) is both comfortable and easy to handle. The rake has been designed to keep your back straighter, while the chainstays have been shortened to ensure the bike's agility when cornering.

      DERAILLEUR AND TRANSMISSION: A SINGLE CHAINRING LIKE THE PROS!

      Discover the efficiency and ease of the single chainring: 1 chainring and 8 speeds. Accelerate on the flat and easily tackle climbs without compromise. With just 1 lever on the handlebar, no need to think! -ROCKRIDER FC ATB 100 single chainring - 32 teeth equipped with 2 chain guides (anti-derailment) -MICROSHIFT RD-M25- l rear derailleur -MICROSHIFT SL-759 right shifter with speed indicator -MICROSHIFT H081 cassette 8 sprockets 11 to 34 teeth -KMC Z8 wide and strong chain

      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 stiffness thanks to U-FIT (WEIGHT ADJUSTER) technology. Simply adjust the number corresponding to your weight (from 55 kg to 105 kg) directly via the dial on the fork.

      27,5" WHEELS AND TIRES FOR DRY GROUNDS

      The ST 120 wheels are forgiving and robust, with 19 mm 27,5 inch double-walled 28-spoke rims. Overcome your first obstacles without fear: small stones, roots, holes and bumps! Because the first rides are on dry terrain, 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 knobs ensure good grip when cornering.

      MECHANICAL DISC BRAKES

      The TEKTRO TKD 160 dual 68 mm mechanical disc brakes provide powerful and progressive braking at the front and rear. As for the TEKTRO brake levers, they are made of aluminum, easy to grip and precise. Just two fingers are enough to brake. 3 or 4 sets of 10 sharp, intermittent brakes are enough to break in your pads. Remember to have your disc brakes serviced once a year.

      HANGER, STEM, HANDLES

      With its stem inclined 10° upwards, the ST 120 mountain bike's cockpit is raised, accessible and comfortable. In detail: -Aluminium stem, 90 mm long, with a 10° angle to provide maximum comfort -Aluminium handlebar, 640 mm wide, for stability and control -Slatted grips, in "soft touch" material, for good grip, soft and pleasant contact.

      SADDLE

      The ST 120's welded saddle mount prevents any saddle movement. And because, after safety, your comfort is our priority, we offer you an exclusive ERGOFIT saddle, wider, with a hammock-shaped profile. Easily adjust your saddle height with the FLEX steel post, 350 mm or 400 mm long (depending on size). Its reduced diameter of 27,2 mm gives your seat a certain flexibility, 30% greater than a conventional solution.

      FLAT PEDALS

      The ROCKRIDER ST 120 mountain bike comes with flat, hard resin mountain bike pedals for added safety and lightness. If your foot slips off the pedal, you'll be less likely to injure yourself.

      TRANSPORT AND STORAGE

      To easily remove/install the front wheel, we've added a quick-release system. Our tip: a bike rack is a simple way to transport your mountain bike without getting your car dirty.

      WHAT SIZE OF MTB TO CHOOSE?

      Several sizes exist: S: between 1,50 m and 1,64 m M: between 1,65 m and 1,74 m L: between 1,75 m and 1,84 m XL: between 1,85 m and 2,00 m To adapt the mountain bike to your size and your morphology, here is our advice: 1/ Sitting on the saddle, you must touch the ground with the tips of your toes. 2/ To adjust the saddle, your knee will be slightly bent with the foot on the pedal in the low position. 3/ If you hesitate between two sizes, choose the larger size.

      ACCESSORIES

      Your ST 120 mountain bike comes with bell, lights, wheel reflectors and pedals. The frame is compatible with: - 300 (ref. 8172767) and 500 (ref. 8172769) center stands - 100 (ref. 8049106) and 500 (ref. 8358133) bottle cages - MTB mudguard kit (ref. 8385291) - 100 (ref. 8347394) and 500 (ref. 8354448) saddle bags - 500 luggage rack (ref. 8364376) - 100 frame baby seat (ref. 8486913 and 8487125), from size M

      COMFORT AND SAFETY

      Your bike's equipment (chain, derailleur, brakes, etc.) will adjust. Take advantage of the free revision within 6 months of purchase. Our technicians will do a 13-point check of your bike. Go to the nearest DECATHLON workshop with your DECATHLON card and/or receipt.

      To easily remove/install the front wheel, we've added a quick-release system. Our tip: a bike rack is a simple way to transport your mountain bike without getting your car dirty.

      WHAT SIZE OF MTB TO CHOOSE?

      Several sizes exist: S: between 1,50 m and 1,64 m M: between 1,65 m and 1,74 m L: between 1,75 m and 1,84 m XL: between 1,85 m and 2,00 m To adapt the mountain bike to your size and your morphology, here is our advice: 1/ Sitting on the saddle, you must touch the ground with the tips of your toes. 2/ To adjust the saddle, your knee will be slightly bent with the foot on the pedal in the low position. 3/ If you hesitate between two sizes, choose the larger size.
