Gravel bikes have gained popularity in recent years, and for a good reason. These versatile bikes are designed to handle a wide range of terrains, from paved roads to dirt and gravel paths. The Triban Gravel 120 and 520 are two popular models from the French cycling brand, Decathlon. In this post, we will compare the two bikes to help you decide which one is best suited for your needs.

Frame and Components

One of the most significant differences between the Gravel 120 and 520 is the frame material. The Gravel 120 features an aluminum frame, while the Gravel 520 is constructed from steel. Aluminum is known for its lightweight and stiff properties, while steel is valued for its durability and comfort.

The Gravel 120 has a more traditional frame design, with a sloping top tube and a slightly relaxed geometry. In contrast, the Gravel 520 has a more modern, aggressive geometry, with a taller head tube and a longer reach. The Gravel 520 also features a carbon fork, which helps to absorb vibrations from rough terrain.

When it comes to components, both bikes use Shimano drivetrain systems, but the Gravel 520 features higher-end components. The Gravel 520 has a Shimano 105 groupset, which is a step up from the Gravel 120’s Shimano Sora groupset. The Gravel 520 also has hydraulic disc brakes, while the Gravel 120 has mechanical disc brakes.

Overall, the Gravel 520’s steel frame and higher-end components give it an edge in terms of durability and performance.

Drivetrain and Brakes

The Gravel 120 and 520 both use Shimano drivetrain systems, but the Gravel 520’s Shimano 105 groupset is a step up from the Gravel 120’s Shimano Sora groupset. The Shimano 105 groupset is a popular choice for road and gravel bikes because of its reliability and performance.

Both bikes have disc brakes, but the Gravel 520 has hydraulic disc brakes, while the Gravel 120 has mechanical disc brakes. Hydraulic disc brakes provide better stopping power and modulation, especially in wet or muddy conditions. Mechanical disc brakes, on the other hand, are easier to maintain and repair.

Wheels and Tires

The wheels and tires on a gravel bike can significantly affect its performance on different terrains. The Gravel 120 and 520 both have 700c wheels, but the Gravel 520 has wider rims, which allow for wider tires. The Gravel 520 comes with 700x36c tires, while the Gravel 120 has 700x35c tires.

Wider tires provide more traction and stability on rough terrain, but they can also be heavier and slower on smooth surfaces. The Gravel 520’s wider tires and rims make it better suited for off-road adventures, while the Gravel 120’s narrower tires and rims make it better suited for road riding.

Riding Experience

The Gravel 120 and 520 offer different riding experiences due to their frame geometry, components, and wheel/tire choices. The Gravel 520’s more aggressive geometry and higher-end components make it a better choice for experienced riders who want to tackle rough terrain at higher speeds. The Gravel 120’s more relaxed geometry and narrower tires make it a better choice for beginners or riders who primarily ride on roads.

In terms of comfort, the Gravel 520’s steel frame and carbon fork provide more vibration damping than the Gravel 120’s aluminum frame and fork. However, comfort is subjective, and some riders may prefer the stiffer feel of the Gravel 120.

When it comes to handling and stability, the Gravel 520’s wider tires and rims provide better traction and control on rough terrain, while the Gravel 120’s narrower tires and rims make it more nimble and responsive on paved roads.

Price and Value

The Gravel 120 and 520 are both affordable gravel bikes, but the Gravel 520’s higher-end components and steel frame make it more expensive. As of this writing, the Gravel 120 is priced at $899, while the Gravel 520 is priced at $1,399.

In terms of value, both bikes offer a lot of features and performance for their price points. The Gravel 120 is a great option for beginners or riders who primarily ride on roads, while the Gravel 520 is a better choice for experienced riders who want to tackle rough terrain at higher speeds.

Conclusion

Triban Gravel 120 and 520 are both excellent bikes that offer different riding experiences. The Gravel 120 is a great option for beginners or riders who primarily ride on roads, while the Gravel 520 is a better choice for experienced riders who want to tackle rough terrain at higher speeds.

If you prioritize durability, comfort, and higher-end components, the Gravel 520 may be the better option for you, even though it comes at a higher price point. However, if you’re on a budget or prefer a more nimble and responsive ride, the Gravel 120 is a great option.

Ultimately, the best way to decide which bike is right for you is to test ride both models and compare their features and performance. We hope this comparison has helped you make a more informed decision. Happy riding!
