Gravel Grinding Greatness: The State Bicycle Co Carbon All-Road v2 Sidewinder Black Bike

There is something undeniably liberating about a bicycle that refuses to be defined by the surface beneath its tires. In the last few years, the gravel cycling movement has shifted from a niche curiosity to the dominant force in drop-bar riding, and for good reason. It represents freedom—the ability to transition from smooth tarmac to fire roads and gnarly singletrack without missing a beat.

State Bicycle Co. has long been a favorite here at The Coolector for their ability to deliver high-performance machines that don’t require a second mortgage, and their latest release, the State Bicycle Co Carbon All-Road v2 Sidewinder Black Bike, essentially rewrites the rulebook on what an adventure-ready rig can do.

The original Carbon All-Road was a massive hit because it democratized carbon gravel performance, but the v2 is not just a fresh coat of paint; it is a complete evolution of the species. Constructed from a lightweight yet incredibly durable blend of T800 and T1000 carbon fiber, the frame is designed to be stiff where you need power transfer and compliant where you need comfort.

The aesthetic is undeniably stealthy, with the “Sidewinder Black” finish offering a sleek, understated look that hides dirt well and looks just as good parked at a coffee shop as it does covered in mud after a 100-mile race. But it is the geometry that truly signals the bike’s intent.

With a shorter head tube and a more aggressive rider positioning, the v2 is built for speed. It is stable enough for loaded bikepacking but agile enough to mix it up in a cyclocross race.

One of the most significant upgrades to this new model is the sheer amount of rubber you can cram into the frame. In the world of gravel, tire volume is king, and the v2 now accommodates a massive 700c x 2.2” tire.

This level of clearance pushes the bike firmly into drop-bar mountain bike territory, allowing riders to tackle terrain that would have previously been off-limits.

If you prefer a smaller wheel, it can also handle up to 2.4” on a 650b setup. Whether you are running the standard included Vittoria tires or swapping in something knobbier, the versatility here is unmatched.

State Bicycle Co. has also paid close attention to the practical needs of the modern adventurer. The frame now features a downtube storage box with a Fidlock magnetic closure system, which includes a neoprene bag for stowing tools, tubes, or snacks inside the frame itself.

This keeps the bike looking clean and lowers the center of gravity. Furthermore, the bike is future-proofed with a Universal Derailleur Hanger (UDH), making it compatible with the latest drivetrain technologies and ensuring that replacement parts are easy to find.

The cable routing strikes a perfect “best of both worlds” balance, with internal routing through the frame and fork for aerodynamics, but external access at the cockpit to save your mechanic from a headache.

Priced at $2399.99, the Carbon All-Road v2 represents incredible value in a market where carbon gravel bikes often cost twice as much. It is equipped with a T47 bottom bracket for increased stiffness and reliability, and for those running a 1x drivetrain, the front derailleur mount is replaced with a sleek aero plate.

With additional mounting points on the fork, top tube, and downtube, this is a machine begging to be loaded up for a multi-day expedition. Hand-assembled to order in Phoenix, Arizona, the Sidewinder Black v2 is a testament to the idea that the best bike is the one that lets you ride anywhere.
