    58/TwentyFour Full Carbon Clinchers

     

    Brake Performance

    Resin

    Better Modulation, Shorter Braking Distances and Increased Heat Tolerance

    Rather than using the consistently failing attempts at reducing the temperature produced by braking, Profile Design rejected what has become accepted practice and instead increased the heat capacity of our materials. Their proprietary high Tg point resin is 30% higher than other “high” Tg resins. A rim that can withstand more heat leads to improved braking performance by allowing consistent heat built up rather than attempting to reduce heat which often decreases braking power.

    Specially Formulated Brake Compund

    Reduces braking distance by 28% compared to Altair models

    Specifically formulated to withstand the same heat their rims could take on, the brake pad compound is specifically formulated for TwentyFour Series wheelsets. Using a specially formulated rubber compound, durometer and friction agent, Profile Design developed a proprietary brake pad resulting in more consistent braking power and reduced braking distances over that of other carbon fiber wheelsets.

     

    Precision-Engineered Materials Every Step of the Way

    Pre-Preg

    Maintaining Material Integrity from the Outset

    Immediately after fusing the resin and carbon, the pre-preg carbon is frozen to maintain integrity. Each roll is sealed, documented, and placed into a temperature and humidity controlled refrigerator with data tracking that ensures accurate a “first-in/first-out” lean manufacturing processes.

     

    Rewriting Manufacturing Procedures

    Auto-Wrapping

    Increased Compaction and Precise Construction

    Profile Design didn’t just take the traditional route and adopt manufacturing procedures available to just anyone; they developed their own. The result? An auto-wrapping procedure no one else in the industry uses, resulting in fewer voids and fewer inconsistencies in the most important areas - the bead, tire bed and brake track. 

    Lay-Up Process

    Stiffer, Stronger and More Impact Resistant

    How do you improve wheel balance? How can you lessen overall weight? These are the critical points Profile Design looked to address when combing through all details of our manufacturing procedures. They developed a lay-up process laying the UD carbon 45° from perpendicular to the brake track, resulting in a composite structure that is stiffer and more impact resistant.

     

    58/TwentyFour Aerodynamics

    The 58/TwentyFour wheels were designed using Computational Fluid Dynamics (CFD) to produce a fast, robust drag profile over all angles of attack. 

    FASTER Wind Tunnel

    Hundreds of hours in the tunnel, 12 rim profile candidates, 500 platform rotations and 21 data points per reading, Profile Design tested using a protocol to pit their wheels against the most challenging environments. They took the top performing profiles, resulting in a 58/TwentyFour wheelset that produced off-the-chart results confirming a robust drag profile even in moderate to significant conditions. 

    Course Modeling

    Wind tunnel tests can tell us how fast wheels are at different angles of attack – but how common are these angles in the courses most important to athletes? Blindly applying tunnel data to the unpredictable force of Mother Nature didn’t quite add up to Profile Design. They took tunnel data one step further and broke down historical World Championship data on the Queen K into 1500 segments, mapping wind speeds, angles and race day conditions measuring the performance of their selected rim profiles every 394 feet.
