The RTS Carbon's J5 Five-Spoke wheels are the most streamlined non-disk wheels available. The front wheel paired with RTS Carbon's rear JD disk wheel is one of the fastest combination for road time trial events.

The 66 mm deep carbon rim profile is the most aerodynamic spoke-wheel available. With its five airfoil spoke sections that transition smoothly to the center of the wheel, this wheel has one of the lowest drag values of any five spoke wheel.

The wheels are designed using T800 fibers to increase rigidity and durability but at the same time remains lighter than previous models. The hubs use smooth japanese stainless steel cartridge bearings with a new hub design that moves the flanges closer to the center of the hub for less frontal surface area on both front and rear wheels.

The Five-Spoke wheels are available for both track and road events in both front and rear tubular models. Each pair of wheels is supplied with titanium quick release skewers.
