3T PRIMO 2 WPNT RIVAL XPLR (S) - Fumo
The iconic bike whose unbeatable aerodynamics and speed changed gravel riding forever, now in a modern evolution.
It all starts with the tyres
To design a fast bike, you have to start with the wheels. Tire choice determines comfort and grip, but also affects aerodynamics and even frame design. And to design around aerodynamics, you need to know the real tire dimensions; the ones you actually measure. That’s what REALFAST aerodynamics means: reality, not theory.
Tire size and shape depend on rim width, tire pressure, and even the accuracy of the manufacturer’s stated dimensions.
So we ran hundreds of tests and measurements to map the actual tire dimensions, what we call WAM (Width As Measured) and RAM (Radius As Measured), and used those numbers to design the frame.
Realfast Aerodynamics
Aerodynamics matter even off-road.
You notice it most when you’re not grinding uphill, but riding on tarmac or smoother gravel. With headwinds or crosswinds, even if your ground speed is moderate, you’re still moving fast relative to the air; and that’s exactly why aerodynamics make a difference.
PRIMO² is also a great road bike in its own right. That’s because we designed, tested, and optimized it not only at 30 mph (48 km/h) the wind tunnel standard for road bikes, but also at a more realistic 20 mph (32 km/h), which better reflects off-road gravel, dirt, and singletrack speeds.
We developed the Squaero profile by testing the bike with knobby tires and even caked in mud.
Key Features
- Sqaero fork airfoil, perfect to guide the airflow around the front wheel and boost fork stiffness.
- Sqareo frame shape complete the aero fork blades
- Dropping the drive-side chainstay improves tire & crank clearance.
- Fits up to 700 x 45mm tires and even 27.5”x51mm (2.0”), while keeping 4mm between any frame part and tire.
