The 3T Discus C 45/40 Wheelset, initially designed for the Exploro, enhances the performance of any gravel bike, turning it into a speed machine. After extensive tunnel testing involving dozens of prototype wheels, the Discus 45 | 40 LTD was born. It boasts a 45mm depth for effective aerodynamics without succumbing to excessive crosswind vulnerabilities. Its 40mm width perfectly complements 35-40mm tires, resulting in unprecedented speed on gravel terrain. While optimized for the 3T Exploro, the Discus 45 | 40 LTD enhances the performance of any gravel bike.

Similar to the Discus 45 | 32 LTD, the Discus 45 | 40 employs the NoseTail design, which condenses 60mm deep rim performance into a 45mm profile. Rim design inherently involves compromises since what's aerodynamic on the front half may not work as effectively when reversed. The NoseTail shape, developed by aerodynamics expert Dave Kennedy and 3T's Head of Design Gerard Vroomen, balances these compromises. It not only mitigates the performance trade-offs but also requires less rim depth while efficiently guiding rear wheel airflow onto the downtube. This feature is particularly beneficial for bikes where the downtube closely interacts with the front tire. Elevate your gravel biking experience with the 3T Discus C 45/40 Wheelset, engineered for speed and versatility.
