Extrema Italia

EXTREMA ITALIA EXTREME TIRES, TOUGH RACES, FAST ADVENTURES

Discover

The Extrema Italia is designed for the worst gravel and/or the most comfort. Aero yet dropper/suspension seatpost compatible, it can fit up to 700x57c tires.

Italia version only.

100% MADE IN ITALY PRODUCTION

The Extrema Italia represents the expansion of our efforts to bring production back to Italy. Using our proprietary filament winding and RTM (resin transfer molding) technology we have developed a highly capable for adventure yet fast for racing bike.

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.

- You can swap MORE Integrale stem lengths without needing to disconnect and bleed the brake hoses.

- You have the freedom to choose any of our 3T INTEGRALE bars to best fit the ergonomics & functionality you desire.

- Should your adventure take you far from home, the MORE stem can be removed completely for travel without the need to disconnect the brake hoses.

- The Extrema paired with the MORE stem is compatible with 1X & 2X Sram and Shimano electronic groupsets

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.

Max clearance information can be found here.

SO WHAT TIRE DO YOU NEED?

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.

Aerodynamics and stability is further improved when Extrema is paired with 3T super-wide 45/40 LTD wheels.

EXTREMA VS RACEMAX ITALIA

While the Racemax Italia 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 RaceMax frameset is fastest with 29”/700c 35-46mm WAM tires. That’s when its top speed rivals the best road bikes out there. 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 is optimized for 29”/700c 50-57mm 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.

Extrema Italia delivers the same Bottom Bracket and Headtube stiffness values we engineered for RaceMax Italia and that we recommend as optimal for a fast gravel platform. Thanks to an updated layup and thinner seattube, the Extrema offers increased vertical compliance compared to the Racemax Italia.

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..
