Specifically formulated to withstand the same heat our rims can take on, our brake pad compound is exclusive for TwentyFour Series wheelsets. Using a specially formulated rubber compound, durometer and friction agent, we developed a proprietary brake pad and reduced braking distances over that of other carbon fiber wheelsets.
"..the braking performance was virtually unchanged in transitions from dry to wet to monsoon left us all but astounded that these could be carbon brake track wheels, and yet they were. In this case, “impressed” is too light a word—we were floored." -Aerogeeks.com
TwentyFour Series hubs are forged from 6061-T6 Aluminum then precision machined with a tolerance of 100th of a millimeter increasing durability, strength and stiffness. The freehub body is machined from 7001-T6 Aluminum then shot peened hard anodized to create an 18% increase in material strength compared to standard aluminum freehubs. This prevents the cassette from digging into the freehub body resulting in better shift performance and increased power transfer.
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 our athletes? Blindly applying tunnel data to the unpredictable force of Mother Nature did not add up to us. We took our tunnel data a step further, and worked with SpeedTheory to break down popular road and triathlon courses into thousands of segments, mapping the performance of our wheels against historical wind speeds, angles and race day conditions around the world. TwentyFour Series wheels continue to come out with distinct advantages across the yaws most commonly encountered not in a lab, but in the real world.
We designed, tested and revised hundreds of rim shapes to find the very nuances that affect crosswind feedback and handling. Partnering with a team of technicians specializing in Computational Fluid Dynamics from golf equipment to race cars, we were able to merge their expansive CFD knowledge with our aerodynamic expertise. Manipulating width, width location, depth and conicity, we sorted through months of generated data to select the highest performing rim profiles.
Rather than use the consistently failing attempts at reducing the temperatures produced by braking, we rejected what has become acceptable practice and instead increased the heat capacity of our materials. Our proprietary high Tg point resin is 30% higher than other “high” Tg resins. A rim that can withstand more heat leads to braking performance unseen on other carbon rims.
