TECHNICAL INFORMATION

THE WOMEN'S ROCKRIDER PROJECT

Fully designed and developed in France at the B'Twin Village (Lille), this MTB is the result of the work of a team of experts and passionate mountain bikers.
The team observed and studied the specific morphology of women, and designed and tested the ST 540 with female mountain bikers involved at every stage of the project.
Our aim is to inspire you to get on your mountain bike and enjoy every ride on a comfortable, easy-to-use mountain bike.

A MOUNTAIN BIKE FOR GIRLS AND WOMEN

We carried out surveys to develop a mountain bike adapted to women's morphology. We carried out: studies with the Decathlon Sports Lab and real-world tests with mountain bikers. 6 months later, this was the result: a mountain bike with positioning elements adapted to women!
- An ergonomic saddle for women's hips.
- A fork that can be adjusted to your weight from 45kg upwards
- Shorter handlebars and an adjustable stem
- Reduced distance between the grips and brake levers

HOW TO CHOOSE YOUR MOUNTAIN BIKE SIZE

This is our guide for MTB sizes!
S: between 1.50m and 1.64m
M: between 1.65m and 1.74m
L: between 1.75m and 1.84m
To adapt your MTB to your height and size, try these tips:
1/ Sitting on the saddle, your 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.

A COMFORTABLE, PLAYFUL FRAME

Because we've noticed that it's not always easy to get the right position on a mountain bike, our designers have created an entirely new frame that's easy to get onto.
The CGF frame (Comfort Geometry Frame) is 100% aluminium for optimal comfort and excellent manoeuvrability. The slope angle has been designed to keep your back straight whilst the low rear ensures the bike is very agile when turning.

FRONT SUSPENSION FOR CUSHIONING LUMPS AND BUMPS


Directly adjust the stiffness of the suspension to your weight, from (45/80kg) to more easily travel over roots and stones. This is possible thanks to the UFIT concept (exclusive to Decathlon).
Easy: simply turn the adjustment wheel.
Designed to overcome rough terrain, the 100mm travel of the fork and the 27.5" wheels allow you to easily travel over most obstacles. The hydraulic disc brakes are powerful and progressive in all weather conditions.

DERAILLEUR & DRIVE TRAIN: HOW TO CHANGE SPEEDS

2 9-speed chainwheels for a wide range of 18 easy-to-use speeds.
2 quick shifters on the handlebar.
Left (chainwheels): control ascents/descents.
Right (speeds): more precise control over your pedalling.
In detail:
-Double chainwheel
-Front Shimano Altus / Acera derailleur
-SRAM X2 rear derailleur
-SRAM x 4 shifters with gear indicators
The axle running through the external bearings ensures excellent rigidity and durability in the long term.

STEM, HANDLEBAR, GRIPS: for comfort

The 60mm-long aluminium stem, which is specially designed for women's bodies with its 10° angle, gives you maximum comfort. Aluminium handlebars are 660 mm ensures stability and control. And the soft touch handles, for good grip, are comfortable to hold.
To adjust the bike even more accurately, you can move the spacer (the coloured ring) to adjust the stem's height, or put it back on to raise the position.

An ERGONOMIC SADDLE that can be easily adjusted

A Comfort Plus women's saddle exclusively adapted for female morphology. The wider, hammock-style design is hollowed out in the centre for comfort. Want an even comfier saddle?
Add a saddle cover. Adjust your saddle height quickly and without tools thanks to the easy adjustment lever.

HYDRAULIC DISC BRAKES: GET A GRIP ON YOUR BRAKING

To adapt to girls' small hands, we have reduced the distance between the handlebar and the brake! With this better, more responsive position, you will gain confidence. The TEKTRO aluminium brake levers are easy to grip, lightweight, and precise.
The double hydraulic disc brakes provide powerful, progressive braking to the front and rear. Just two fingers are all you need to brake.
Try to get your brakes adjusted at least once a year.

27.5" wheels & tyres for dry terrain: READY TO ROLL?

Take on your first obstacles! The Aero Trail Evo aluminium wheels are efficient and robust: 27.5" with double-walled rims. Their diameter offers an excellent balance between performance and comfort. With their 28 spokes, they are lightweight, stiff, and durable.The exclusive, wide B'Twin All Conditions 27.5"x2.2 tyres are suitable for dry terrain. The side lugs provide grip on turns. The recommended tyre pressure according to the weight of the rider is marked on the tyre sidewall.

PLATFORM PEDALS

The ST 540 is supplied with platform MTB pedals mounted on bearings, made from resin for lightness and safety. If your foot slides on the pedal, there's less risk of injury.

EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE

Not all rides start on your doorstep. Need to remove the front wheel?
It's easy thanks to the integrated clamping lever. And the rear wheel? There is a nut at the back to secure the bike and limit the risk of theft.
A flat spanner is needed to remove the rear wheel.
A bike carrier will make your life easier if you want to avoid dirtying your car.

ACCESSORIES

Your ST 540 mountain bike is supplied with a bell, lights, wheel reflectors and pedals.
The frame is compatible with:
- front and rear mudguards,
- stand,
- bottle cage,
- saddle bag,
- rear pannier rack,
- child seat (add an additional pannier rack for sizes S and M to avoid touching the rear wheel)
etc.

OUR ADVICE FOR YOUR FIRST FEW RIDES

To get yourself equipped, we recommend wearing cropped bottoms, shorts or cycling shorts with a pad (a saddle-shaped foam insert), or a gel saddle cover to improve your comfort as you ride. For longer rides, it's always a good idea to take something to keep yourself hydrated (e.g.: a hydration bladder or bottle).
And finally, a tip for safety with a touch of style: even for short rides, wearing a helmet and gloves are key to preventing injury

Stickers for an easy-to-understand MTB

Did you notice the coloured stickers over your mountain bike? Don't worry, it's not to add a touch of pink.
Resistant to wear, they provide hints on how to adjust your bike: adjusting the fork, tyre pressure, rim diameter, saddle height... When you head off on a ride, it's always useful to have the instructions directly on your bike!
