The Cobblestone offers a range of Shimano components in the standard configuration, including GRX (1x12 and 2x12), Ultegra, Dura-Ace, and electronic Di2 shifting

4. Comfortable and enduring rides
Thanks to its asymmetrical frame design, the Cobblestone allows for exceptionally short cranks, enhancing comfort. Additionally, the shock-absorbing Selle Italia saddle ensures a smooth ride.

5. Versatile and durable
The Cobblestone’s carbon frame is exceptionally stiff and highly durable. It includes multiple mounting points for fenders, racks, bottle cages, and other accessories, making it highly adaptable to your needs.

What Differentiates Gravel Bikes from Cyclocross Bikes?

Gravel bikes and cyclocross bikes cater to a similar trend, both designed for off-road use and non-paved routes. Gravel bikes generally offer more comfort, while cyclocross bikes - with their lower center of gravity and aggressive geometry - are better suited for rugged terrain. Cyclocross bikes are closer to mountain bikes than gravel bikes in their design and focus.

Key Features of a Gravel Bike

Gravel bikes are designed for rides off the beaten path and new adventures. They are perfect for cyclists who love exploring nature and tackling challenges. Key features of gravel bikes include:

Frame and Geometry: Made of carbon, this gravel bike frame is built for stability and comfort on uneven terrain. The geometry is more relaxed than that of road bikes, offering a more comfortable riding position.

Tires: Gravel bikes feature wider tires, typically between 35mm and 45mm, for better traction and comfort on gravel and unpaved roads while maintaining efficiency on asphalt.

Brakes: Disc brakes are standard on gravel bikes, providing reliable stopping power in all weather conditions, which is essential for off-road riding.

Gearing: Gravel bikes are equipped with wide-range gearing systems to tackle steep climbs and maintain speed on descents.
