Unisex frame

With a very marked slope on the top tube and a wide range of sizes (from XS:1.40m to XL:2.00m),The ST 100 mountain bike frame is UNISEX.The ST 100 mountain bike exists with the same frame in a WOMEN'S version: 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.

A lightweight, comfortable, fun frame

It isn't always easy to get the right position on a mountain bike. Our designers created a frame that's easy to get onto.The 100% aluminium CGF frame (Comfort Geometry Frame) is both comfortable and easy to handle. The slope angle has been designed to keep your back straight, while the rear bases were shortened to make the bike very agile in turns.

Derailleur and drive train

3 x 7 speed chainrings, 21 speeds total!2 easy-to-use grip shifters on the handlebars.Left (chainrings): control ascents/descents.Right (speeds): more precise control over your pedalling.Details: -Triple-chainring chainset (22/32/42 teeth) + protection / grease.-MICROSHIFT FD-M20 FRONT derailleur-MICROSHIFT RD-M25 REAR derailleur-MICROSHIFT MS25 grip shifters with speed indicators-SHIMANO TZ500 7 cog cassette, 14 to 28 teeth-Large, solid KMC Z51 chain

Front suspension

The 80 mm front suspension helps you overcome your first obstacles on slightly uneven trails with no worries.Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain.

27.5" wheels & tyres for dry terrain

The wheels of the ST 100 are tolerant and robust, with 27.5" double-walled 28-spoke rims (26" for the XS size). Slow down without worrying about obstacles: small rocks, cracks, holes and bumps!Because you're getting started with MTB touring on dry ground, this mountain bike is equipped with DRY 27.5 x 2.0 tyres. Their performance is optimised thanks to the rounded central section, whilst the side lugs provide good grip on turns.

V-brakes with pads

Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.Thanks to the special design of the ST 100's aluminium brake levers, you only need two fingers to brake.One a year, check how the pads are wearing. If the grooves are disappearing, take your bike to your local store's workshop.

Handlebars, stem, grips

With a stem that tilts 10° upwards, the riding position of the ST 100 is raised, accessible, and comfortable.In detail:-Aluminium stem, 90mm long, with a 10° angle for maximum comfort.-620mm wide steel handlebar, for stability and control.-Grips in "soft touch" material' for good grip and a soft comfortable feel.

Saddle

The saddle of the ST 100 is welded to prevent any movement of the saddle.And because your comfort is our priority after your safety, we've added an exclusive wider Ergofit saddle with a hammock shape.Easily adjust the height of your saddle with the Flex steel seat post, either 350mm or 400mm long (according to the bike size). Its reduced diameter of 27.2mm provides your seat with natural flexibility, 30% more than a standard solution.

Platform pedals

The Rockrider ST 100 mountain bike is supplied with hard resin platform mountain bike pedals for added lightness and safety.If your foot slides on the pedal, there's less risk of injury.

Transport and storage

We added a quick release system for easily attaching/removing the front wheel.There is a nut at the back to secure the bike and limit the risk of theft. You will need a spanner to remove the back wheel.Our advice: a bike rack is an easy way to transport your mountain bike without dirtying your car.
