OPTIMUM HEAT DISSIPATION

RELIABLE PERFORMANCE FROM CYCLOCROSS TO DOWNHILL

HIGH DURABILITY, EVEN IN THE TOUGHEST CONDITIONS

2. HEAT AND STRUCTURE SIMULATIONS

Heat transfer within the design concepts was studied extensively using engineering simulation software. The relationships between convection, radiation, surface area and weight were used to determine the optimal design to maximize heat dissipation and strength while minimizing weight. The structure of each design was evaluated under braking forces ranging from typical hand pressure up to theoretical maximums. Critical pressure points in the structure were identified in order to maximize the strength and stiffness of the rotor.

3. AIRFLOW ANALYSIS

Computational fluid dynamics (CFD) simulations were performed to study airflow over the surface of the rotor and through the cut-outs. A variety of profiles were tested to determine the effects of asymetrical holes and optimize the cooling effect of airflow over the surfaces.

Thermodynamic simulations, structural analysis and fluid dynamic visualizations were conducted in collaboration with the Institute for Energy Technology at HSR University of Applied Science.

4. FINAL DESIGN

The final design was confirmed and visualized with further thermal and structural simulations.

A two piece design consisting of a 7075-T6 aluminum alloy spider and SUS410 stainless steel brake track was chosen to balance light weight with reliable thermal management and structural performance.

Vibrations are minimized by the geometry of the brake pad contact area.

5. LABORATORY TESTING

Laboratory testing of the Catalyst disc rotor confirmed the results of the engineering simulations.

The Catalyst excels in endurance testing - delivering consistent brake torque over time while standard brake systems gradually decline and eventually suffer structural failure.

Further tests demonstrated extremely efficient thermal management, notably shorter stopping distances, very low wear rates and structural integrity under hard braking exceeding the current industry leaders.

Practical testing of the prototypes allowed the development team to determine the optimum balance between two of the primary, yet competing, characteristics: brake performance and weight.

A carefully chosen few extra grams of material added to the outer ring translated directly into shorter stopping distances.

Engineers selectively added material to specific sizes to further improve performance and durability.
