The latest offering from FLO Cycling is the new FLO 30, a shallower wheelset meant for training, road racing, and generally as an all-around wheel that will take anything you can throw at it. Unlike the 60, 90, and Disc wheels that FLO offers, the new 30 is all aluminum, with no fairing. It's meant to be an incredibly robust, durable product. You can swap it out for your deeper FLO wheels without needing to adjust your brakes at all, which will make it an incredibly attractive product for existing FLO customers.
The 30mm-deep rims are ideal as training wheels, but the aero shape will still save time if you choose to race with them.
