FLO 45 Carbon Clincher Rim

$199 $399
The all new FLO 45 Carbon Clincher. Ultra lightweight, nearly invisible to cross winds, and faster than our first generation FLO 90 at only half the depth. Perfect for climbing, road racing, and recreational riding.

CREATING A BASELINE
3D Modeling
We created a highly accurate model of the tire/rim interface, by molding a tire mounted to a FLO rim. This tire/rim model was combined with our 2012 rim profiles to create a baseline for our new design work. Learn more about our
3D Modeling Process

DEVELOPED WITH CD-ADAPCO ENGINEERS
Optimization Algorithm
Using a list of design parameters and the data collected from our 110,000 data points, we built a custom optimization algorithm. This algorithm ran on CD-adapco's Super Computer and intelligenty tested and refined 500 prototypes to find the fastest rims shapes possible. Using a standard desktop computer, these calculations would have taken 4.5 years to complete. Learn more about our

Time Savings with FLO Wheels

The below time savings were calculated using our Net Drag Reduction Value (NDRV) equation. The NDRV equation is designed to give cyclists an accurate estimate of expected time savings using FLO wheels. Learn more about our Net Drag Reduction Value equation.
