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.

• 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.

– 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

Features:
– 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, stems, grips:
– with a stem that tilts 10 upwards, the riding position of the st 100 is raised, accessible, and comfortable.

• 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.

What size mountain bike to choose?
– xs: between 1.40m and 1.54m
– s: between 1.55m and 1.64m
– m: between 1.65m and 1.74m

To adapt the bike to your height and size, try these tips:
– sitting on the saddle, you should be able to touch the ground with the tips of your toes.
– to adjust the saddle height, your knee should be slightly flexed with the foot on the pedal in the lowest position.
– if you’re between two sizes, choose the larger size.

Storage tips:
– after washing, rub with a dry cloth to remove all traces of moisture. Store your mountain bike in a cool, dry place, away from corrosive products and salty air.
– restrictions on use: not suitable for xc, all mountain, enduro and bmx.
