Extremely Capable — Extremely Fast

Handmade in their new Italian carbon factory, the 3T Extrema Italia frameset is designed to be the centerpiece of an ultra premium bike for the toughest race courses and fastest adventures. The Extrema sets itself apart from its more aero cousin the Racemax by incorporating features that crank up the toughness and adjust the geometry for a more comfortable and capable ride without compromising speed and performance.

In the world of gravel, the first question is always, "how big are the tires?" And it's here that the Extrema aims to be a new standard. This frame accepts 700c/29" wheels with a WAM (Width-as-Measured) of 57 mm. That means that 29er tires up to 2.2", giving the Extrema the same grip as top of the line cross-country mountain bikes but with a drop bar geo and riding position. So with almost any tire available, the choice is yours. The Extrema can be your fast adventure bike for wild epics or it can be your racing bike for the longest, roughest challenges out there. Then again, it can just be both!

The Finer Details

The Extrema is designed for speed on climbs, flats, and descents. Plus it responds well even on the most technical terrain, allowing you to stay wheels down and reduce hike-a-bikes. Its "3Touring geometry" lands squarely in the performance zone for gravel even though it guarantees increased comfort relative to aggressive race bikes, making it a fantastic option for an all-road long distance event where a more relaxed and comfortable position is essential.

The Extrema's round seat tube allows for a dropper or suspension seatpost, making it the perfect bike to have fun on more technical trails and descents. As the rest of the frame tubes are aero, you're sure not to lose any time along the way.

To further boost its aero credentials, the Extrema uses 3Ts Integrale internal cable routing system and MORE carbon stem. This gives you internal cables from start to finish while allowing quick stem adjustments and changes. And by using an integrated yet 2-piece carbon stem & bar, you can pick the handlebar size and shape of your choice independent of the stem.
