Data Driven Design

Rim Shapes Optimized Using Real World Data

Using 110,000 data points collected while riding on the road, we developed a custom optimization algorithm that intelligenty tested 500 prototypes to find the fastest rims shapes we've ever created. For more information on this process, visit our Aero page.

FLO Aero Data



* All wheels tested at the A2 Wind Tunnel with a 700c x 23mm Continental GP4000S II tire.

* Tunnel wind speed set to 30mph.

* Tare removed. Learn More.

* Mavic Open Pro was a front wheel with 32 round spokes and a 700c x 23mm Continental GP4000s II tire.

* Aero numbers were gathered using our pre built front FLO 45 Carbon Clincher with Sapim CX-Ray spokes and our FLO VORTEX 2 Hub.

Time Savings with FLO Wheels

Wheel 40k Ironman
2013 FLO 30 38s 2m 51s
2016 FLO 60 Aluminum + Carbon 55s 4m 9s
2016 FLO 90 Aluminum + Carbon 1m 0s 4m 29s
2016 FLO DISC Aluminum + Carbon 1m 14s 5m 31s
2016 FLO 45 Carbon Clincher 55s 4m 6s
2016 FLO 60 Carbon Clincher 1m 3s 4m 41s
2016 FLO 90 Carbon Clincher 1m 4s 4m 48s
2016 FLO DISC Carbon Clincher 1m 11s 5m 19s

* Time savings were calculated using our pre built front FLO 45 Carbon Clincher with Sapim CX-Ray spokes and our FLO VORTEX 2 Hub.

The above 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.

What People are Saying

"What a story they are telling with these wheels. The design process was, as far as I can see, the most comprehensive and advanced this industry has ever seen, bar none."

"When you look closely at the data and run these new wheels through the models, they are aerodynamically as sound than anything created by the big players in the industry. What sets FLO apart is that their wheels come in at half the price without sacrificing performance."

"When a company tells you their new product is 2-3% faster than their original, you take notice. When FLO tells us that their new FLO 60 Carbon Clincher is 22.20% faster than their previous model, you shut up and ask whom to make the check out to."
