Suspension Fork

The model is built on a lightweight aluminum frame and comes equipped with 27.5-inch wheels. Its classification as a mountain bike is evidenced by the presence of an SR Suntour front suspension fork with up to 80mm of travel. Despite the absence of a lockout function, the fork practically does not reduce the efficiency of power transfer while pedaling, maintaining comfort in rough terrain.

Transmission Based on Microshift Components

The bicycle can be equipped with a 21-speed transmission assembled from entry-level Microshift components. There are also model modifications with 9 speeds, so it is advisable to verify exact specifications with the retailer. Gear shifting is facilitated through a grip shift lever mounted on the straight handlebar.

Mechanical Disc Brakes

The bike is fitted with Tektro disc brakes featuring a mechanical drive. They provide reliable braking even in challenging weather conditions and emergencies. An additional advantage of the Rockrider ST120 model is its affordable price, making it an attractive choice for beginner riders.
