With a heavily sloped top tube and a wide range of sizes (from S: 1.50 m to XL: 2 m),The ST 540 V2 mountain bike frame is UNISEX.The ST 540 V2 mountain bike also exists in a WOMEN'S variant V1: fitted seat, narrower handlebar, shorter stem, fork with a more flexible spring, and brake levers that are closer together.As a woman, if you choose the men's model, we recommend at least purchasing the Women's Sport 500 saddle which is fitted to the female form.

We created this ST 540 V2 mountain bike entirely at our B'Twin Village (Lille, France) for mountain biking enthusiasts.A comfortable, efficient mountain bike: more progressive, powerful hydraulic disc brakes, 100mm hydraulic fork to easily and sensitively ride over obstacles, and simple and high-performance single chainring...MTBers have been involved at every stage of this bike's development process.

For less weight and more efficient pedalling, the Rockrider ST 540 V2 frame is made from 6061 aluminium (2.1 kg in size M). Our designers have designed and developed it so it is comfortable and easy to manoeuvre. We worked with the Sports Lab (our R&D centre) to keep the rider's back straight for a very comfortable mountain biking position.The lower bottom bracket helps keep you more stable during turns.

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

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: the mountain bike is lighter; less energy is lost on flatter ground. If however your primary concern is comfort and manoeuvrability, the ST 540 is available in a full suspension version with suspension at the rear.

Efficient and easy:1 chainring and 10 speeds:Accelerate on the flats and easily tackle the climbs. 1 single shifter on the handlebar: adapt your speed instantly as the terrain changes!Details: -ROCKRIDER FC ATB 500 32-tooth single chainring-MICROSHIFT ADVENTX 10-speed rear derailleur with long cage-MICROSHIFT ADVENTX right shifter-MICROSHIFT ADVENTX 10-cog cassette (11-48 teeth)-KMC X10 chain

Our teams designed and created an exclusive ROCKRIDER ERGOFIT saddle. Designed for all hip widths, its hammock shape is very comfortable for long, athletic 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.

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

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 wide, ROCKRIDER ALL CONDITIONS (60 TPI) 27.5" x 2.1 tyres have side knobs designed for riding on all types of terrain (dry, wet, etc.).Tubeless Ready 23 mm rims: SCHRADER valves, TUBELESS rim tape, TUBELESS tyres, and puncture-proof liquid to be added.

The ST 540 V2 comes with Rockrider Flat platform pedals with a wider pedalling surface and more pronounced dots for better grip on the pedal.
