TECHNICAL INFORMATION

WHAT SIZE MOUNTAIN BIKE TO CHOOSE?

There are several sizes available for this ST 900 Women's mountain bike:
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

If you're on the borderline between 2 sizes:
Choose the smaller size for better handling (easier to handle) and comfort (straighter back).
Choose the larger size for better pedaling and a more extended position (better performance).

A MOUNTAIN BIKE ADAPTED TO WOMEN'S MORPHOLOGY

For even more comfort, the women on our MTB team have designed an ST900 MTB to suit your feminine morphology:

The ergonomic saddle is hollowed out in the middle for greater seating comfort.
The fork is adjustable from 45 kilos upwards for smoother suspension and more riding pleasure.
The handlebars are narrower to suit shoulder width.
The brake levers are closer together: easier to grip.
The stem is 60mm shorter for a better position.

A WORD FROM THE TEAM

Passionate about mountain biking, we designed and developed this ST 900 mountain bike entirely in France at BTWIN VILLAGE (Lille). A comfortable, efficient mountain bike: 120 mm ROCKSHOX fork, for easy overcoming of obstacles, ... fork lockable on the handlebars, single chainring and 27.5" double-walled wheels lightened for efficiency.
Women mountain bikers were involved in every stage of the project to validate this ST 900 mountain bike.

A LIGHTWEIGHT, COMFORTABLE AND PLAYFUL FRAME

For greater lightness and efficient pedaling, the frame of the ROCKRIDER ST 900 mountain bike has been designed in 6061 aluminum (only 1.6kg in size M). It's 300 grams lighter than the ST 540 frame, thanks to its "double butted" front triangle.

Our designers have designed it to be comfortable and easy to handle. Its inclination has been designed to keep your back more upright. Thanks to its lower bottom bracket, you'll be more stable when cornering.

ROCKSHOX 120MM FRONT SUSPENSION

The 120-hydraulic ROCKSHOX 30 SILVER fork mm is 400 grams lighter than that of the ST 540 mountain bike.

With its conical shape, it provides even greater rigidity and precise trajectory control. It can be adjusted to its weight using a conversion table.

Adjust the fork's hardness and rebound easily (using a conversion table).
The fork's handlebar lock (COMBO LOCK) prevents pumping and loss of speed on rolling terrain.

DERAILLEUR & TRANSMISSION: A SINGLE CHAINRING LIKE THE PROS!

Discover the ease and efficiency of the single chainring.
1 chainring and 11 gears: accelerate on the flat and tackle climbs easily without compromise.
1 single shifter on the handlebars: you can adapt your speed instantly, like the pros, to the hazards of the terrain!

In detail:
-Single chainring SRAM X1 32 teeth
-Rear derailleur MICROSHIFT M665 11 speeds
-Right shifter MICROSHIFT M8515
-Cassette MICROSHIFT H113 11 sprockets 11 to 46 teeth
-Chain KMC X11

HANDLEBARS, STEM, HANDLES

With its adjustable stem, the controls of the ST 900 women's bike are at your fingertips.
All-aluminum, the 60mm stem ROCKRIDER (sizes S, M and L ) can be raised using 5 adjustment levels.
In detail:
-Aluminum 680 mm
-Ergonomic ROCKRIDER handlebars, for a good grip and pleasant contact
-Brake levers 1cm closer together because women's hands are smaller on average. More comfortable braking position.

COMFORTABLE & SPORTY SADDLE / SEATPOST

Our teams have imagined and designed an ergonomic women's saddle ROCKRIDER "Women Confort sport":
Adapted to the female pelvis, its profile is "hammock" shaped. It is hollowed out in the center and profiled to avoid chafing and irritation for your mountain bike outings of 3 hours or more.

With the 27.2 mm diameter aluminum FLEX saddle post, this contributes to a high level of comfort.

Adjust the height of your saddle quickly and without tools, thanks to the easy-to-use adjustment lever on the saddle clamp.

HYDRAULIC DISC BRAKES

No matter what conditions you're riding in (wet or dry), the dual hydraulic disc brakes ROCKRIDER by TEKTRO of 180 mm for the front and 160 mm for the rear, are there for you, even in the mud.

Hydraulic braking gives you more power and progressiveness, and much less muscular effort to apply to the levers.
The aluminum brake levers are easy to grip, light and precise.

27.5" LIGHTENED WHEELS, LIGHT AND WIDE TIRES

The 27.5" wheels are lightened double-walled. Their sleeved rims, combined with lightened tires, are 230g lighter than on the ST 540.

With 28 spokes, they are light, stiff and resistant.
The exclusive ROCKRIDER ALL CONDITIONS LIGHT 27.5 "x2.2 tires have lateral studs for all-terrain use. A 2.2 width means more grip on technical sections.

TUBELESS READY rims: you'll need rim tape, special valves and puncture-proof fluid.

TRANSPORT & STORE YOUR MOUNTAIN BIKE EASILY

We've made it easy to remove and install the front and rear wheels. They are equipped with a tool-free quick-release system (clamping levers).
