3T Primo² WPNT (GRX 1 x 12Speed)

The Original Fast Gravel Bike, Evolved.

The 3T Primo² WPNT GRX 1X is a unidirectional pre-preg carbon speed machine, hand-painted in Italy and designed to bridge the gap between a high-end road bike and a world-class gravel racer. With the WPNT philosophy, it’s engineered to remain aerodynamically efficient whether you're running fast 35mm road slicks or 45mm gravel knobbies, making it the ultimate "one-bike" solution for the rider who refuses to slow down when the pavement ends.

Why the Primo² WPNT is the Ultimate All-Road Weapon:

• RealFast Aerodynamics: Unlike road-only aero bikes, the Primo² is optimized for "real-world" speeds (32 km/h) and wide tires. Its massive Squaero downtube (50x75mm) shields water bottles and guides airflow around front-wheel turbulence.

• Semi-Integrale Cable System: Debuting on the Primo², this system hides the cables within the cockpit and frame for a super-clean aesthetic and aerodynamic advantage, while remaining much easier to service than fully integrated setups.

• Upgraded Stack Height: For the SS26 generation, 3T has added 1.5cm of stack to the geometry, providing a more comfortable, slightly more relaxed position that’s perfect for long-distance gravel adventures without losing that sharp "road" feel.

• Shimano GRX 1x12 Performance: Outfitted with the latest Shimano GRX 822/610 components, providing the silent security of a clutch-driven 1x drivetrain with a massive 10-51T gear range to conquer any elevation.

• Extreme Versatility: While optimized for 700c x 45mm tires, the frame is fully compatible with 650b wheels and tires up to 2.1” (51mm), allowing you to transform the bike into a mini-monster-cross machine for technical terrain.

• UDH Compatibility: The frame is Universal Derailleur Hanger (UDH) ready, ensuring you have access to the most common hanger standard in the world and full compatibility with the latest drivetrain technology.

The Alegro Perspective: In the shop, we call the Primo² the "honest gravel bike." It doesn't pretend to be a mountain bike; it feels like a road bike that just happened to grow some teeth. If you spend 50% of your ride on pavement getting to the gravel, this bike is going to feel significantly faster than a traditional "adventure" bike. The new Semi-Integrale cable routing finally gives it the high-end look it deserves without making a handlebar adjustment a three-hour ordeal.
