WHAT SIZE OF MTB TO CHOOSE?
Several sizes exist:
S: between 1.50m and 1.64m
M: between 1.65m and 1.74m
To adapt the mountain bike to your size and morphology, here are our tips:
1/ Sitting on the saddle, you must touch the ground with your tiptoes.
2/ To adjust the saddle, your knee will be slightly bent with your foot on the pedal in the low position.
3/ If you hesitate between two sizes, choose the larger size.
MIXED FRAMEWORK
With a very marked top tube inclination, over a very wide range of sizes (from S: 1m50 to M: 1m74 ),
the frame of the ST 120 mountain bike is MIXED.
The ST 120 mountain bike is available with the same frame.
If, as a WOMAN, you choose the MEN's model, we recommend that you purchase at least the SPORT FEMME 500 saddle, adapted to the female morphology.
TEAM WORD
Passionate about mountain biking, we have entirely designed and developed this ST 120 mountain bike in France at BTWIN VILLAGE (Lille).
Recreational mountain bikers have expressed to us their need for comfort, efficiency and robustness. From there, we designed, designed and tested the ST 120 mountain bike, involving them at all stages of the project.
LIGHTWEIGHT, COMFORTABLE AND PLAYFUL FRAME
Our designers have designed a brand new frame that is easy to step over.
This 100% aluminum CGF (Comfort Geometry Frame) frame is both comfortable and easy to handle. The inclination has been studied to keep your back straighter while the rear chainstays are shortened to ensure good agility of the bike in turns.
FRONT SUSPENSION
The 80 mm front suspension allows you to overcome your first obstacles with peace of mind on slightly uneven trails.
REAR SUSPENSION: NONE
This mountain bike has no rear suspension.
It is a so-called "semi-rigid" mountain bike: ideal for beginners and embarking on your first mountain bike rides.
Faced with a "full suspension" MTB (with rear suspension), the interest is simple: the MTB is lighter; you lose less energy on flat ground.
DERAILLEUR & TRANSMISSION: A SINGLE CHAINRING LIKE THE PROS!
Discover the efficiency and ease of the single chainring:
1 chainring and 9 speeds.
Accelerate on the flat and tackle climbs with ease without compromise.
With just 1 controller on the handlebar, you no longer need to think!
- ATB 500 single chainring
- 36 teeth equipped with 1 chain guide (anti-derailment)
-MICROSHIFT RD-M46-L rear derailleur
- MICROSHIFT SL-M759R right shifter with speedometer
-MICROSHIFT H092 Cassette 9 cogs 11 to 36 teeth
-Wide and strong KMC Z9 chain
HANDLEBAR, STEM, GRIPS
With its stem inclined 15° upwards, the cockpit of the ST 120 mountain bike is raised, accessible and comfortable
In detail :
- Aluminum stem, 60 mm long, with a 15° angle to provide maximum comfort
-620mm aluminum handlebar, for stability and control
- Slatted handles, in "soft touch" material, for a good grip, a soft and pleasant contact.
SADDLE
Your comfort is our priority, we offer you an exclusive ERGOFIT saddle, wider, with a profile in the shape of a hammock.
Easily adjust your saddle height with the 350 mm long steel FLEX post . Its reduced diameter of 27.2 mm gives your seat a natural flexibility.
MECHANICAL DISC BRAKES
The TEKTRO TKD 116 double 160 mm mechanical disc brakes exert 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.
Remember to have your disc brakes serviced once a year.
27.5" WHEELS & TIRES FOR DRY TERRAIN
The wheels of the ST 120 are tolerant and robust, with 19 mm 27.5 inch double wall rims with 28 spokes.
Cross your first obstacles without fear: small stones, roots, 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.
FLAT PEDALS
The ROCKRIDER ST 120 MTB comes with hard resin flat MTB pedals for lightness and safety.
If your foot slips off the pedal, you will be less likely to injure yourself.
TRANSPORT & STORAGE
To disassemble / mount the front wheel easily, we have added a quick release system.
Our tip: a bike carrier is a simple way to transport your mountain bike easily, without dirtying your car.
