TECHNICAL INFORMATION

A WORD FROM THE TEAM

This ST 540 mountain bike has been entirely designed and developed at the B'Twin Village in France (Lillle). A comfortable, efficient mountain bike: more progressive, powerful hydraulic disc brakes, 100mm travel in the fork to easily travel over obstacles, simple, effective double chainwheels,...
MTBers have been involved at every stage of this bike's development process.
And we hope that the Rockrider ST 540 helps you make the most of your MTB tours.

A UNISEX MOUNTAIN BIKE

Men's or women's mountain bike?
This Rockrider ST 540 mountain bike is unisex.
For greater comfort, the women on our mountain bike team recommend replacing the saddle with the Women's 500 Sport saddle, which is adapted to women's bodies.
A range of Rockrider mountain bikes specifically designed to fit female morphology is also available (specialised saddle, stem, fork and brake grips).

HOW TO CHOOSE YOUR MOUNTAIN BIKE SIZE

Several sizes available:
S: between 1.50m and 1.64m
M: between 1.65m and 1.74m
L: between 1.75m and 1.84m
XL: between 1.85 m and 2.00 m
If you are on the limit between 2 sizes:
Choose the smaller size for easier steering (easier to handle) and comfort (straighter back).
Choose the larger size for easier pedalling with a more stretched-out position (position more suited to performance).

A COMFORTABLE, PLAYFUL FRAME

For a lighter weight and more efficient pedalling, the Rockrider ST 540 frame has been designed with 6061 aluminium (only 1.9 kg in size M). Our designers have designed and developed it so it is comfortable and easy to manoeuvre. Its slope has been designed to keep your back straighter. The lower bottom bracket helps keep you more stable during turns.

THE FRONT 100MM SUSPENSION

Confront all obstacles with the hydraulic fork. Its 100 mm travel allows you to calmly move over more obstacles (roots, pebbles, stones, mud).
Its built-in lockout system helps to prevent bobbing and loss of speed on faster terrain.

REAR SUSPENSION: NONE

This mountain bike has no rear suspension. This is a "semi-rigid" mountain bike.
Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: lighter weight, you will spend less energy on flat ground. If however you're looking for comfort and manoeuvrability, the ST 540 is available in a full suspension version with suspension at the rear.

DOUBLE CHAINWHEEL DERAILLEUR AND DRIVETRAIN

2 9-speed chainwheels for 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
- Microshift front derailleur
- Shimano Altus rear derailleur
- Shimano Acera shifters with speed indicators
The bottom bracket for through-axles guarantees excellent rigidity and durability over time.

HANDLEBARS, STEM, GRIPS

The adjustable stem brings the controls for the ST 540 easily under your hands. The all-aluminium B'Twin stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised using 5 adjustment intervals: + 0mm, + 7.5mm, + 15mm, + 22.5mm, + 30mm.
In detail:
- 720mm oversized aluminium B'TWIN SPORT handlebars
- Soft touch B'TWIN SPORT grips for good grip and a comfortable feel.

COMFORTABLE, SPORT SEAT POST AND SADDLE

Our teams have conceived and designed an exclusive B'Twin Ergofit Evo saddle. Designed for all hip widths, its hammock shape is very comfortable for long sports rides. The Flex 27.2mm diameter aluminium seatpost also contributes to its increased level of comfort.
Quick and easy tool-free adjustment of your saddle height using the adjustment lever on the seat post clamp.

HYDRAULIC DISC BRAKES

No matter what conditions you ride in (dry/wet), the Rockrider by Tektro 160mm double hydraulic disc brakes will come through for you, even in the mud.
Hydraulic braking adds more power and progressive braking and requires less powerful use of the brake levers.
The aluminium brake levers are easy to grip, lightweight, and precise.

27.5" WHEELS WITH DOUBLE-WALLED RIMS AND TYRES FOR ALL CONDITIONS

The aluminium wheels are effective and sturdy: 27.5" diameter and double-walled rims. Their diameter is the perfect balance between comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.
The exclusive wide Rockrider All Conditions 27.5"x2.2 tyres are suitable for dry/wet 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 B'Twin Flat platform pedals with a wider pedalling surface and more pronounced dots for better grip on the pedal.

EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE

Not all rides start on your doorstep. This is why we've made it easy to remove and attach the front and rear wheels. They are equipped with a quick-release system.

ACCESSORIES

Your RR540 mountain bike comes with a bell, lighting, wheel reflectors, and pedals.
The frame is compatible with:
- Front and rear mudguards
- Stand
- Bottle cage
- Saddle bag
- Rear pannier rack
- Child seat
etc.
