3T - PRIMO WPNT
GRX 1×12 700c ALLOY

WPNT = WE PAINT!

WPNT means “We Paint” and marks the opening of 3T’s new paint facility in Montella, near their headquarters. It’s the final piece of the puzzle that gives 3T full control over the entire production process—from carbon fiber to finished bike. With in-house painting, they can offer more color options even in small quantities, which was not possible with Asian suppliers. Delivery times for custom builds are now faster—just 6–8 weeks. And the carbon footprint is lower due to less shipping.

SQAERO

A wide 50 mm downtube catches air from the front tire—but a deep full airfoil would be inefficient. That’s why 3T designed the Sqaero shape. With a 50×75 mm profile, Sqaero balances aerodynamics and stiffness. This shape also shields your bottles. You’ll find it all over the Primo frame.

PRIMO versus RACEMAX, EXTREMA and ULTRA

RaceMax, Ultra and Extrema are built for gravel, each with unique strengths. Primo is different: it brings road-bike DNA with gravel adaptability. Ride it with fast 700c wheels or swap to 650b for rough terrain. Primo is your all-rounder—versatile, elegant, and ready for any road.

REALFAST AERODYNAMICS

Aerodynamics matter—even on gravel. You may go slow off-road, but on tarmac, speed returns. And wind resistance never takes a break. 3T tested Primo at 32 km/h, with bottles and mud. Real-world conditions. The result? Primo is faster dirty with 40 mm gravel tires than clean bikes with 28 mm slicks.

WHAT’S MY FRAME SIZE?

Sing the right bike size is crucial for a comfortable and enjoyable ride. Use this chart to pick the size which fits your body. Please note, this is merely a suggestion. For the best results, we recommend a professional bike fitting with an expert.

IT ALL STARTS WITH THE TIRES

To build the fastest bike possible, you start with the tires. They define grip and comfort—and how the frame can guide airflow. But printed sizes lie. 3T measured hundreds of tires to get their real-world widths (WAM) and radii (RAM). With this data, Primo is built to fit road, gravel and even wide 650b tires when adventure calls.

SQUAREO HEADTUBE, DOWNTUBE AND SEATTUBE

Squaero frame shapes complete the aero fork blades.

DROP CHAINSTAY ON DRIVE SIDE

Dropping the drive-side chainstay improves tire & crank clearance.

TIRE CLEARANCE

THREADED BB

All the Primo complete bikes come with threaded BBs without any alloy rings in the carbon (avoiding added weight, complexity and debonding risk).

RITCHEY RAIL CLAMP

Available for round and oval rails.

2 BOTTLE POSITION DOWNTUBE

When using one bottle cage, go for the lowest downtube position for the best aero advantage
