A wide tire needs a wide rim to avoid turbulence in the tire-rim transition, so the 3T Discus 45 | 40 is the first aero wheel designed for 35-40mm tires. A 29mm internal width makes your chosen tire even wider & reduces tire flop.
After testing two dozen prototype wheels in the tunnel, the Discus 45 | 40 LTD was born. 45mm deep for good aerodynamics without excessive crosswind vulnerability. 40mm wide to match up those 35-40mm tires. The result is speed never seen before on gravel roads. And while the shape is optimized for the 3T Exploro, the Discus 45 | 40 LTD makes any gravel bike faster.
Similar to other 3T wheels, the Discus 45 | 40 uses the NoseTail design to squeeze 60mm deep rim performance in a 45mm profile.
By definition rim design is a compromise, because whatever shape is aerodynamic on the front half doesn't work so well 180 degrees later when it's backwards. The NoseTail shape was developed by the legendary Dave Kennedy (an aerodynamics professional for over 50 years) and 3T's Head of Design Gerard Vroomen. The NoseTail actually sacrifices some performance on the front half of the wheel in favor of working better on the back half.
Not only do the two effects cancel each other out, but the resulting shape also requires less rim depth and better guides the airflow from the rear of the front wheel onto the downtube. This is particularly helpful on the Exploro RaceMax where the downtube is positioned in close proximity to the front tire.
