Up to 700x57c tire

Up to 700x57c tire clearance for the same traction as a top of the line cross-country MTB

Internal Storage

The clean design is enhanced by two new integration features:

The downtube houses a storage compartment that shields tools and tubes from the elements, with a wide opening and a secure and stable Fidlock closure.

Triple mounts on the fork legs

3t More Integrale Technology

Running cables internally can be nice and potentially reduce aero drag, but what is the point if you end up with a very wide and bulky headtube with oversized bearings to house the cables? Also, usually integrated systems make maintenance and rider position adjustments a nightmare.

Our MORE Integrale system uses the exact same headtube shape for internal and external cables and gives you all the benefits without the drawbacks:

- You can make small height adjustments to the MORE Integrale without disconnecting or resizing the brake hoses.

It All Starts with the Tires

To make the fastest possible gravel bike, you need to start with the tires. Tire choice determines comfort & grip, but it also determines how you can shape the frame to redirect airflow.

To aerodynamically engineer the frame around the tires, you need to know what their REAL measurements are. Not what’s on the label, but how they really fit. That’s REALFAST aerodynamics. It’s not easy however, as the tire dimension depends on the rim you use, tire pressure, and of course how accurate the manufacturer’s claimed size is.

We took hundreds of measurements to know the real tire widths (which we call WAM - Width As Measured and RAM - Radius As Measured) and engineered the frame around that data.

Realfast Aerodynamics

Balancing aerodynamic efficiency with the demands of rugged gravel terrain requires meticulous engineering. The challenge lies in optimizing the bike’s aerodynamics without compromising its ability to tackle variable surfaces. The Extrema is optimized around massive 29”/700c tires with 50-57mm WAM (Width-As-Measured).

Our solution is a downtube design that cleans up the airflow mess as it passes over the front wheel and meets the frame. The downtube is 60mm wide right behind the front tire and gets even wider as it gets close to the BB. This redirects the airflow over the frame from the front wheel and shields the bottles for a complete aerodynamic system.

Additionally, the head-tube features an elongated aero profile with an aggressive truncation at the back. This creates a sharper front end that’s is much narrower between the two headset bearings. These features paired with your riding position make for an adventure bike that is seriously fast and ready for anything.

Extrema Vs Racemax Italia

While the Racemax²Italia focuses on fast courses and tarmac/gravel mixed riding, the Extrema Italia is designed exactly as it sounds: for the toughest race courses and fast adventures.The Racemax²Italia frameset has been engineered and aerodynamically optimised to deliver its best performance in combination with tires ranging from 41 to 51 mm. . So whether you’re on asphalt, easy or tougher gravel, you can be sure you have the fastest setup.

The Extrema offers even more traction and control as it has been engineered to excel with 29”/700c 47-57mm WAM tires. It is designed for the toughest terrain at high speed for long rides.

The Extrema features our 3Touring geometry with a higher stack and shorter reach when compared to Racemax to make the Extrema the ideal choice for adventure racing and bikepacking adventures. The wireless dropper and suspension seatpost compatibility along with fork accessory mounts add to the versatility of this unstoppable race adventure bike.

3touring Geometry

Our new 3Touring geometry consists of 2 parts: rider fit and handling.

The rider fit is optimized for tougher terrain. This means that while the rider position is still road-inspired for the fastest rider position, the stack is a little higher to offer better control over your bike. The changes are subtle.

The handling geometry is quite extreme, to ensure that the bike inspires confidence on rough terrain but still feels light and nimble on fast sections despite the massive tires. A slightly slacker headtube angle and extreme fork offset (61-73mm depending on frame size!!!) gives you a very familiar handling even on very unfamiliar terrain.

Internal Storage with Fidlock Mechanism

The compartment is easily accessible and secured with a lid featuring a Fidlock “Mini‑hook” fastening mechanism. Locking and unlocking the lid is done via a small closure lever located directly on the cover.Inside the storage compartment, a removable neoprene bag developed in collaboration with Missgrape ensures firm, secure stowage of items, free from unwanted vibrations.

60mm Downtube Neck

Upper downtube necks down to 60mm to pick up the airflow coming off the front tire.

Downtube Shape and Storage

The lower section is 75 mm wide, designed to streamline airflow not only around the bottles but also around the tools stored in the integrated storage compartment.

The Fidlock mini-hook locking mechanism ensures super-easy opening and secure closure with just a click, while the Missgrape-developed neoprene bag guarantees silent, stable load carrying. It’s also easy to remove thanks to the integrated handle. [Link to instruction]
