Brake Performance

The 1/Fifty is a wide, deep profile, full carbon aero rim that successfully blends crosswind stability, stiffness and handling while delivering superior heat dissipation and braking performance by utilizing the same ultra high Tg resin and brake pads as the TwentyFour series wheels.

Precision-Engineered Materials Every Step of the Way

The semi-automated carbon lay-up, rim construction and raw materials proven through the TwentyFour series wheels are exemplified in the 1/Fifty rims. By utilizing components optimized for more efficient production, we are able to deliver a performance wheelset at an aggressive price.

"…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'
