Like the standard Jet, only way better.
The new version is built on our C2 rim extrusion. C2 is alloyed with Scandium, which makes it lighter than the old version, which is nice; but what really excites us is what a wider rim does to the tire.
On a 23mm wide rim, the tire beads are farther apart and the tire profile is shorter and rounder. Put a 20 or (especially) a 23mm tire on a 19mm rim and the resulting profile looks more or less like a lightbulb. Even with an aero rim behind it, the wind still "sees" a bulb at both ends of the wheel. On the C2 wheels, a 20mm tire looks like a bullet, and even a 23 does not hang over the brake surface. The wind "sees" a smoother shape. The result is that you are faster.
C2 has:
- Lower drag. The airflow is more laminar and less turbulent as it transitions from the tire surface to the rim surface (and from rim to tire on the trailing edge of the wheel).
- Lower rolling resistance. Widening out the tire improves the shape of the contact patch, making it shorter front to back, and wider. A shorter contact patch means that a smaller section of sidewall deflects at the ground. Less sidewall deflection - lower rolling resistance.
- Vastly improved cornering, sprinting, and out of the saddle climbing. Cornering is better because there is more rubber in contact with the road, and just as important. the straightened sidewalls don't flex as much under hard cornering. With less sidewall flex, sprinting and out of the saddle climbing both more efficient since less energy is lost to tire flex.
