Gravel bikes have become increasingly popular over the past few years due to their versatility and ability to handle different types of terrain. The Topstone series by Cannondale has been a popular choice among gravel bike enthusiasts, and the Topstone 3 and Topstone 4 are two of the latest models in the series. In this article, we will compare and contrast the Topstone 3 and Topstone 4 to help you decide which one is the better option for you.
Design and Frame
The design and frame of a bike are crucial to its performance and ride quality. The Topstone 3 and Topstone 4 have different frame materials and geometry that affect their performance on different terrain types.
The Topstone 3 features an aluminum frame, while the Topstone 4 has a carbon frame. The carbon frame of the Topstone 4 is lighter than the aluminum frame of the Topstone 3, making it easier to handle on steep climbs and rough terrain. The Topstone 4’s carbon frame is also more durable and can handle more wear and tear than the Topstone 3’s aluminum frame.
The geometry of the two bikes is also different. The Topstone 3 has a more relaxed geometry that makes it more comfortable for longer rides, while the Topstone 4 has a more aggressive geometry that makes it more suitable for faster, more technical riding.
The Topstone 3 can accommodate tires up to 700x37c, while the Topstone 4 can accommodate tires up to 700x42c. The Topstone 4 also has the option to switch to 650b wheels, which can accommodate even larger tires.
Overall, if you’re looking for a bike that’s more lightweight and designed for more technical riding, the Topstone 4 is the better option. If you prefer a more comfortable ride for longer distances, the Topstone 3 may be the better choice.
Components and Features
The components and features of a bike can make a big difference in its performance and functionality. Let’s compare the Topstone 3 and Topstone 4 to see how they differ in this aspect.
Drivetrain and Brakes
The Topstone 3 and Topstone 4 both have Shimano GRX groupsets, which are specifically designed for gravel bikes. The Topstone 3 has a 2×10 drivetrain with a 46/30 crankset and an 11-34 cassette, while the Topstone 4 has a 1×11 drivetrain with a 40t chainring and an 11-42 cassette.
The 1×11 drivetrain of the Topstone 4 offers simpler shifting and eliminates the need for a front derailleur, making it easier to maintain. However, the 2×10 drivetrain of the Topstone 3 offers more gear options for different riding conditions.
Both bikes have hydraulic disc brakes, with the Topstone 3 featuring Shimano GRX 400 and the Topstone 4 featuring Shimano GRX 600. The GRX 600 brakes of the Topstone 4 provide better stopping power and are more durable than the GRX 400 brakes of the Topstone 3.
Suspension System and Handlebars
The Topstone 3 has a Cannondale SAVE carbon seatpost and a Cannondale 3 alloy handlebar, while the Topstone 4 has a Cannondale SAVE carbon seatpost and a Cannondale 3 alloy butted flare drop handlebar.
The Topstone 4 also has a suspension system called the Kingpin suspension system, which adds more comfort and stability to the ride. The Topstone 3 does not have a suspension system, so it may not be as comfortable to ride on rough terrain.
Additional Features
The Topstone 4 comes with a few additional features that the Topstone 3 does not have. It has an integrated wheel sensor that connects to the Cannondale app to track your rides and provide information on battery life, as well as a hidden cable routing system that gives the bike a cleaner, more streamlined look.
Overall, if you prioritize simplicity and flexibility in your drivetrain, the Topstone 4 may be the better option. If you prefer a more comfortable ride with added features, the Topstone 4 is the way to go.
Performance and Ride Quality
The performance and ride quality of a bike is perhaps the most important aspect to consider when deciding between two models. Let’s take a look at how the Topstone 3 and Topstone 4 perform on different types of terrain.
The Topstone 3’s relaxed geometry and aluminum frame make it a great option for longer rides on smoother terrain. Its 2×10 drivetrain also offers plenty of gearing options for tackling hills and headwinds. However, it may not perform as well on rough or technical terrain due to its lack of a suspension system.
On the other hand, the Topstone 4’s carbon frame, more aggressive geometry, and Kingpin suspension system make it a better option for technical terrain and fast descents. Its 1×11 drivetrain also simplifies shifting and reduces the chances of chain drops. The larger tire clearance also allows for more versatility in choosing the right tire for different types of terrain.
Overall, the Topstone 4 offers better performance and ride quality on rough or technical terrain, while the Topstone 3 is better suited for longer, smoother rides.
Price and Value
The Topstone 3 and Topstone 4 are both great bikes, but they come at different price points. The Topstone 3 retails at around $1,750, while the Topstone 4 retails at around $2,750.
While the Topstone 4 is more expensive, it comes with several features and upgrades that may justify the higher price point. However, if you’re on a tighter budget, the Topstone 3 still offers excellent value for its price.
Conclusion
Choosing between the Topstone 3 and Topstone 4 ultimately depends on your individual needs and preferences. The Topstone 3 is a great option for longer rides on smoother terrain, while the Topstone 4 is better suited for rough or technical terrain. The Topstone 4 also comes with several upgrades and features that make it worth the higher price point.
No matter which model you choose, the Topstone series is a great choice for anyone looking for a versatile and reliable gravel bike.
