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. Easily adjust the hardness using U-Fit technology (weight adjuster). Simply set the number to your weight (55 kg to 105 kg) using the dial on the fork.
-
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: the mountain bike is lighter; you spend less energy on flat ground.

Tires
The 27.5" wheels of the ST 120 are tolerant and sturdy, with 19 mm double-walled rims with 28 spokes. Start overcoming obstacles fearlessly, including small rocks, cracks, holes and bumps! Because your first rides will be on dry ground, the Dry 27.5 x 2.0 tyres are most suitable. The central section has low rolling resistance (faster), while the side lugs provide good grip on turns.
Cockpit and contact points
-
Saddle
The saddle of the ST 120 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.
