We do not sell prebuilt wheels with Powertap hubs. We sell individual FLO rims, that you can build your own Powertap into.
All of our wheels were designed with a 23mm x 700c tire. The fastest tire we have tested in the A2 wind tunnel with our wheels, is the Continental GP 4000s II in a 23mm x 700c size.
Currently we only offer 700c wheels. We do not have immediate plans to sell 650c wheels.
We do not sell tubular wheels and currently have no plans to do so.
No. We are not able to offer fewer spokes or unique lacing patterns at this time.
All of our Carbon Clincher model wheels have structural carbon fiber. All of our Aluminum + Carbon, and Aluminum wheels use an aluminum rim as the structural component of the wheel. Our Aluminum + Carbon wheels also have a non structural carbon fiber fairing for improved aerodynamics.
The following rims can be purchased by themselves. All other wheels are sold as a complete build only.
Sold as Rim Only
FLO quick release skewers are compatible with most modern day bicycle frames. FLO quick release skewers may be incompatible with older bicycle frames, classic frames and frames with semi-horizontal dropouts. Please contact us or a qualified bicycle mechanic if you have questions.
Proper tire pressure varies on tire size and rider weight. Please see our tire pressure blog article that describes this topic in detail.
All of our wheels are designed and built to be used for both training and racing.
Aluminum and Aluminum + Carbon Wheels
All Aluminum and Aluminum + Carbon wheels in the list below should use aluminum rated alloy brake pads. Wheels damaged as a result of using the wrong brake pads will not be covered by warranty.
Carbon Clincher Wheels
All Carbon Clincher wheels listed will come with FLO brake pads that MUST be used with our wheels in order to maintain the warranty. Use of any brake pads other than FLO brake pads on Carbon Clincher wheels will void the warranty.
The braking performance of carbon clincher wheels is highly dependent upon the epoxy resin system and brake pads used. Our FLO brake pads have been formulated to work our epoxy resin system which optimizes braking. In our ride tests, we do not feel there is a noticeable difference between braking performance when comparing our Carbon Clincher wheels to our Aluminum and Aluminum + Carbon wheels.
Our Carbon Clincher wheels use a combination of UD, and 3K carbon fiber. Our Carbon Clincher wheels have mainly a UD carbon fiber appearance, and the 3K carbon fiber is used in key locations for structural purposes. Our Aluminum + Carbon wheels use all 3K carbon fiber. All wheels have a matte finish.
All FLO rims are proprietary and designed in house by FLO.
Our aluminum rims are anodized with a black finish. This has no performance effect on the wheel and does not effect braking.
The black anodization will eventually wear off of your aluminum rim. The rate at which this occurs depends primarily on the weather conditions. In dry conditions, the finish can last for years. In wet conditions, the finish can begin to wear off in as little as one ride.
We use Sapim CX-Ray spokes in all of our wheels except for our FLO DISC wheels. The FLO DISC wheels use Sapim Laser spokes. This is simply because a disc wheel does not benefit from an "aero" spoke.
All of our FLO front wheels have 20 spokes in a radial pattern. Our standard rear wheels have 24 spokes in a 2 cross pattern, and our clydesdale rear wheels have 28 spokes in a 3 cross pattern.
All of our spokes are Silver. We currently do not offer black spokes.
We use high quality FLO VORTEX and FLO VORTEX 2 hubs constructed with 7075 aluminum. Here is a video showing how our hubs are made.
We use Japanese EZO Stainless Steel bearings.
You can read more about our bearings here on our blog.
