The Disc » The FLO Disc is based off of the design of the FLO 90, with the remainder of the wheel (the spoke fairing) optimized independently. This results in some strange-looking shapes, but an undeniably fast wheel.

Today, FLO Cycling has introduced an entirely new lineup of wheels. They're keeping their signature low prices, introducing some new amazing wheels in both carbon clincher and their former hybrid alloy-plus-fairing formats. Moreover, the new wheels have been designed with what can only be described as an absolutely cutting-edge design process that involved iterative algorithmic shape generation and testing. That is, a computer was given certain design parameters, and automatically generated and cycled through hundreds of different shapes, testing each one in CFD to arrive on the fastest shape consistent with FLO's real-world yaw statistic.

The Dream Team 

I was fortunate to review a whole collection of the new wheels, including a FLO 45 front, 60 front, 60 rear, 90 rear, and Disc. This dream team of five wheels clocks in at the price of one pair of wheels from a competitor, and covers virtually every imaginable training and racing situation.

The Details 

FLO makes their own hubs, compatible with 10 and 11-speed cassettes. These are user serviceable, even on the disc, and are all laced with Sapim CX-ray spokes (except the discs, which get Sapim Laser spokes).
