Features and Performance

Design and Build: The Rockrider ST 120 boasts a 100% aluminium frame, ensuring a lightweight yet sturdy build. This not only enhances the bike's speed but also ensures durability, making it perfect for those gnarly trails.

Single Chainring: Simplifying the biking experience, the single chainring ensures precision and ease of handling. Whether you're climbing steep trails or shredding through flat terrains, the bike's mechanism promises a smooth ride.

Braking System: Safety is paramount when you're hammering down trails, and the Rockrider ST 120 doesn't compromise. Equipped with Tektro TKD 68 160mm disc brakes, it ensures immediate stopping power, giving riders the confidence to tackle any trail.

Suspension: While it's a semi-stiff model tailored for less-experienced riders, it comes with a front suspension system. This ensures a comfortable ride, absorbing shocks from uneven terrains.

In-depth Comparisons

The Rockrider ST 120, when compared to its sibling, the Rockrider ST 900, showcases some distinct differences. While both bikes cater to the beginner segment, the ST 120 is more budget-friendly, making it an ideal choice for those just starting out. The ST 120's aluminium frame and single chainring drivetrain offer simplicity and efficiency. However, when it comes to downhill performance, the ST 120 might lag behind its competitors. Yet, its Tektro brake system offers unparalleled stopping power, often requiring deeper pockets in other models.

Rider Experience

The Rockrider ST 120 is not just a entry level bike; it's a well thought out workhorse. Designed for commutes and easy terrain, it promises a fun ride. The 430 mm short chainstays make the bike playful, allowing for more maneuverability in tighter corners. Its seating position strikes a balance between sporty and comfortable, ensuring you won't tire out easily. However, when it comes to hardcore downhill trails, it's advisable to reign it in a bit and remember this is a general purpose bike.
