Reserve 42/49 DT 180 SP Disc Wheelset

Developed and tested using Turbulent Aero technology, the Reserve 42/49 DT 350 SP Disc Wheelset offer unmatched all-day performance combined with aerodynamic efficiency. Proven in World Tour races like Paris-Roubaix and Giro d’Italia, these wheels come with a lifetime warranty and a no-fault crash replacement, ensuring peace of mind for cyclists of all levels. In line with Reserve's commitment to reliability, the 42/49 features external nipples, standard spokes, and a semi-hooked design that imposes no tyre limitations and has no rider weight limits.

The Reserve 42/49 wheelset development begins with Computational Fluid Dynamics (CFD) to maximise aerodynamics while ensuring enhanced stability. This is followed by wind tunnel testing to simulate real-world airflow, providing precise data to validate performance goals in a controlled environment. The result is one of the most aerodynamic and stable wheelsets available, delivering top-tier performance in varied conditions, whether racing or training.

The 42/49 wheel creation process begins at Reserve's California composites lab in Santa Cruz, where the carbon fibre layup is developed, alongside a proprietary test protocol designed to mimic real-world impacts and spoke pull-outs. This allows Reserve to optimise the fibre orientation of each rim model, ensuring maximum stiffness and strength. Internally reinforced spoke holes provide additional strength in critical areas without adding unnecessary weight, making the 42/49 wheels a perfect blend of durability, aerodynamics, and performance.
