Rider Type

Is this wheel for you?

Triathlon/Time Trial

The rear FLO 90 Carbon Clincher is one of the most versatile rear wheel for triathletes and time trialists. It's a very aerodynamic race wheel that gets even faster with a wheel cover. Athletes looking for an even faster rear wheel should consider our Carbon Clincher FLO DISC. If you are looking for a more affordable option, consider our Aluminum + Carbon FLO 90 or FLO DISC.

Road Racing

The rear FLO 90 Carbon Clincher makes an excellent rear wheel for crits and stages races because it is very aerodynamic. Those looking for a shallower option, may consider our Carbon Clincher FLO 45 or FLO 60. For a more affordable option, consider our Aluminum + Carbon FLO 60 or FLO 90, or our Aluminum FLO 30.

Recreational

The rear FLO 90 Carbon Clincher is not our first recommendation for recreational riding. Our Carbon Clincher FLO 45, or FLO 60, would be better choices. For a more affordable option, consider our Aluminum + Carbon FLO 60, or our Aluminum FLO 30.

What's best for me? Carbon Clincher OR Aluminum + Carbon?

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.

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."
