FRONT SUSPENSION
The 80 mm front suspension allows you to tackle your first obstacles with complete peace of mind on slightly uneven trails.
Adjust the hardness easily with U-FIT (WEIGHT ADJUSTER) technology. Simply adjust the number corresponding to your weight (from 55 Kg to 105 Kg) directly via the knob on the fork.
27.5" WHEELS AND DRY-WEATHER TIRES
The ST 120's wheels are forgiving and robust, with 19 mm 27.5-inch double-wall 28-spoke rims.
Fearlessly tackle your first obstacles: small stones, roots, holes and bumps!
DRY 27.5 x 2.0 tires are ideal for first rides on dry terrain. Their performance is optimized thanks to a highly rolling central section, while their lateral studs ensure good grip on bends.
MECHANICAL DISC BRAKES
Dual 160 mm mechanical disc brakes TEKTRO TKD 68 deliver powerful, progressive braking front and rear. As for the TEKTRO brake levers: they are made of aluminum, easy to grip and precise. Two fingers are all you need for braking.
3 or 4 sets of 10 dry, intermittent brake applications are all you need to break in your brake pads.
Remember to have your disc brakes serviced once a year.
HANDLEBARS, STEM, HANDLES
With its 10° upward-tilted stem, the ST 120 ATV's cockpit is high, accessible and comfortable.
Details:
Aluminium stem, length 90 mm, with a 10° angle for maximum comfort
Aluminum handlebars, 640 mm wide, for stability and control
Soft-touch siped grips for good grip and soft, pleasant contact.
SADDLE
The ST 120's welded saddle clamp prevents 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 stem, length 350 mm or 400 mm (depending on size). Its reduced diameter of 27.2 mm gives your seat a degree of flexibility that's 30% greater than a conventional solution.
FLAT PEDALS
The ROCKRIDER ST 120 mountain bike comes with flat, hard resin mountain bike pedals for added lightness and safety.
If your foot slips off the pedal, you'll have less risk of injury.
TRANSPORT AND STORAGE
We've added a quick-release system for easy removal and installation of the front wheel.
Our tip: a bike rack is a simple way of transporting your mountain bike without getting your car dirty.
