Components
Parts found in a manufacturer catalog show their brand, model and key numbers, and the steps show how precisely they are identified: brand, series, model, or the exact product. The info button has every detail and the text the manufacturer published.
Suspension
-
Fork
The 80 mm front suspension helps you get started with overcoming obstacles on slightly uneven trails easily. Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain. To adjust the stiffness? It's very easy using a single dial.
-
Rear shock
This mountain bike has no rear suspension. It is a "semi-stiff" mountain bike: perfect for beginners launching themselves into their first mountain bike touring rides. Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: this mountain bike is lighter; you spend less energy on flat ground.
Brakes
-
Brakes
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.

"27.5 inch"

Tires
The wheels of the ST 100 are tolerant and robust, with 27.5" double-walled 28-spoke rims (26" for the XS size). Start overcoming obstacles fearlessly, including 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.
Cockpit and contact points
-
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 (350mm or 400mm long depending on the bike size). Its smaller 27.2mm diameter provides your seat with natural flexibility, 30% more than a standard solution.
