This mountain bike has been designed by us especially for women getting started with mountain biking, for rides of up to 90 minutes in dry weather.

Designed and developed entirely in France at the B'Twin Village (Lille). The team studied the features of the female form and used this to design and test the ST 540 MTB, involving women mountain bikers at every stage of the process. Our goal is to make you want to ride and enjoy every single outing on a comfortable and easy-to-ride mountain bike.

A Mountain Bike Designed For Women. We carried out studies to create a mountain bike specially designed for women. These included studies with the Decathlon Sports Lab, and real-world tests with hard-core women mountain bikers.

6 months later, this was the result: a bike with positioning elements designed for women! An ergonomic saddle designed for the female pelvis. A fork that can be adjusted to your weight, from 45kg upwards. Shorter handlebar and a 60 mm adjustable stem.

Grips and brake levers moved closer together. A Comfortable, Playful Frame. For added comfort on our ST 540 women's model, our designers created a frame that's easy to get onto.

The CGF frame (Comfort Geometry Frame), made of 100% aluminium, provides excellent comfort and manoeuvrability. The slope is designed to keep your back straighter, so you can ride without neck pain, while the shorter rear bases make the bike more agile in turns. Front Suspension For Cushioning Lumps And Bumps.

Adjust the suspension hardness based on your weight (45 kg on up), to get over roots and stones more easily (UFIT technology exclusively patented by Decathlon). Just turn one dial and you're done! Nice and easy. Designed for riding on rough terrain, the fork's 100mm travel and the 27.5" wheels allow you to easily ride over most obstacles.

The hydraulic disc brakes are powerful and progressive in all weather conditions.

Derailleur & Drivetrain: How To Change Speeds. 2 9-speed chainrings provide a wide range of 18 speeds that are easier to use.

2 quick shifters that are easy to use: control ascents / descents.

Right (speeds): more precise control over your pedalling.

In detail: Double chainring.

Shimano Altus / Acera front derailleur. SRAM X2 rear derailleur. SRAM X4 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 shorter 60mm aluminium stem, which is specially designed for the female form with a 10 degrees angle, delivers maximum comfort.

The 680 mm wide aluminium handlebar provides good control and stability. And the soft touch handles are comfortable to hold and provide good grip. To adjust the bike to your build, move the spacer (the coloured ring) to adjust the stem's height, or turn it over to raise it.

An ERGONOMIC SADDLE that adjusts in one step. An exclusive women's "COMFORT PLUS" saddle designed especially for the female pelvis. 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 using the quick-adjust lever.

HYDRAULIC DISC BRAKES: GET A GRIP ON YOUR BRAKING. To better fit women's smaller hands, we reduced the distance between the handlebar and the brake by 1 cm. This more responsive position will help you build confidence as you ride.

The Tektro aluminium brake levers are easy to grip, lightweight, and precise. The double hydraulic disc brakes provide powerful, progressive braking at the front and rear. The brakes can be applied using only two fingers.

We recommend that you have your brakes checked at least once a year.

27.5" WHEELS & TYRES FOR DRY GROUND: READY TO RIDE?.

Take on your first obstacles! The AEROTRAIL Evo aluminium wheels are effective and sturdy: 27.5" with double-walled rims.

Their diameter offers an excellent balance of performance and comfort. With 28 spokes, they are lightweight, stiff, and durable. The exclusive B'Twin All Conditions 27.5"x2.2 wide tyres are designed for dry terrain.

The side knobs provide grip on turns. The recommended tyre pressure, based on the weight of the rider, is marked on the tyre sidewall. PLATFORM PEDALS.

The women's ST 540 comes with platform MTB pedals mounted on bearings, made from hard resin for light weight and safety. If your foot slides on the pedal, there's less risk of injury.

Weight: S - 155-164cm : 13.5 kg.

M - 165-174cm : 13.95 kg.

L - 175-184cm : 14.05 kg. Weight without pedals.

B'Twin Bikes

B'Twin are a popular choice of bike in the UK, partly due to their widespread distribution by Decathlon, and partly due to the value they offer. Their bikes are divided into several slightly overlapping ranges, with Triban best known for road and gravel bikes, and Rockrider gaining a reputation for high performing MTBs to suit every budget. Elops largely consist of a range of city bikes, whereas Riverside focus on hybrids. All in all, B'Twin bikes are well worth checking out given the size of their ranges; there's a model to suit most budgets.

Rockrider Mountain Bikes

Rockrider are Decathlon's off-road offerings, comprising of a series of kids bikes and adult hardtails, full suspension steeds and even a handful of high end E-MTBs.

This brand was launched in 2018, when Decathlon decided to split their B'Twin bikes into different genres. In terms of prices, there's something for everyone, with adult's MTBs starting at just over £200 and rising up to high end lightweight race bikes at nearly the £4000 mark.

If you want to ride off-road, and would prefer to buy from Decathlon, then the Rockrider mountain bike range is for you.
