Precision-Engineered Materials Every Step of the Way

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.

Hub

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.

CFD Engineered Rim Profiles

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.

"…rivaled the acceleration and overall performance of the lighter and significantly more expensive wheels."

"On long descents, the quality of the braking was excellent. The pads weren't too grabby, and when a hard stop was required, the stopping distance was on par with an aluminum brake track." - Active.com
Featured 9/16/14 BICYCLING Magazine's Gear of the Day: “The TwentyFour series carbon clinchers are a light, aerodynamic wheel, with braking performance that is on par with wheelsets that are twice the price....they became my go-to, everyday wheelset.”
"Braking with the 38/TwentyFour wheels was solid and strong, while the modulation afforded by the included brake pads allowed me to gradually slow—or stop quickly—with confidence.” -Road Bike Action, July issue
"These wheels feel more planted to the ground more than any other carbon clincher I've ridden."
-Road Bike Action, July issue
"Competitive weight, good braking, ‘fast’ to ride on, comes with everything you need to get going and all at a lower price – what’s not to like?" -BICYCLING Australia, September issue
"..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 'First Ride'
"Either Profile Design equipped these wheels with tiny motors or they’re naturally disconcertingly quick...We aren’t sure what mojo Profile Design has worked on the braking surface of the 24 Series, but we are reasonably certain that it involves black magic." - AeroGeeks.com 'Final Thoughts'
