Primo² — The Icon Evolved The iconic bike whose unbeatable aerodynamics and speed changed gravel riding forever — now in a modern evolution. WE PAINT! Our advanced carbon technology lets the material itself shine as a design element, yet we know colour is how a 3T bike truly expresses personality and style. That’s why we invest deeply in crafting original graphics, selecting premium paints, and developing striking finishes. Because colour defines a bike’s identity and character, we brought all painting in-house at our factory in Presezzo, Italy. Today, every 3T frame is painted in Italy. With our in-house paint facility and the WPNT custom program, we now own the full creative process — from engineering to colour design. REALFAST AERODYNAMICS Aerodynamics matter, even off-road. You feel it most when you’re not grinding uphill — on tarmac or smooth gravel. In headwinds or crosswinds, even at moderate ground speed, you’re moving fast through the air. That’s exactly where aerodynamics make the difference. Primo² is also a formidable road bike in its own right. We designed, tested, and optimised it not only at the wind-tunnel standard of 48 km/h (30 mph), but also at a far more realistic 32 km/h (20 mph) — matching real gravel, dirt, and singletrack speeds. We developed our Squaero shape by testing the bike fully equipped with knobby tyres — and even caked in mud. SQUAERO PROFILE Primo²’s aerodynamic performance begins with the down tube. At 50 × 75 mm with a truncated Squaero profile, it delivers ideal stiffness and the perfect shape to guide airflow around wide front tyres. A full airfoil starting from the required 50 mm width would need a height of 150–200 mm — creating excessive surface drag. Our truncated Squaero profile keeps drag low and even shields your water bottles from airflow. To deliver REALFAST aerodynamics across the whole bike, we applied the Squaero profile not only to the down tube — but also to the head tube, fork, seatpost, and seat stays. Primo² vs. Racemax · Extrema · Ultra Racemax & Extrema Italia: built with gravel-first geometry Racemax: the ultimate choice for fast gravel and racing — when speed is everything Extrema Italia: built for non-stop ultra-adventure and the toughest off-road races Ultra: blends extreme terrain clearance with efficient aerodynamics Primo² takes a different path — road-inspired geometry, with full support for wide tyres and both wheel standards. Ride fast on 700c wheels; swap to 650b with larger tyres when adventure calls. Your Primo² is ready for anything.
