When we decided to produce the Rosa we had one aim in mind. A true track wheel has to withstand a huge amount of fatigue and yet must remain true and responsive at all times. Also, to meet the needs of track and club riders, the rear hub is double sided, starting with fixed gears on both sides and easily convertible to a freewheel.
First of all, the spokes are forged from the finest Swedish stainless steel and CNC machined to ensure the threads are precisely correct. The nipples are CNC machined so that when the wheel is built, the angle between the spoke and nipple is minimal when tension is applied during building. (Take a look at how many wheels you see in the market where the angle of the nipple and spoke exceeds 5 degrees).
The hubs are CNC machined and fitted with EZO bearings to provide a much lower rolling resistance. During the Copenhagen 6 day, riders using Pro-Lite track wheels commented on how smooth the wheels ran and how noticeable it was to feel the acceleration through them.
As with the rest of the wheels in our range, each wheel is carefully built by hand to extremely precise tolerances. Each spoke is tension checked six times during building and then we de-tension the wheel twice before final truing. Also, the rear hub is double sided, with fixed gears on both sides, which makes it ideal as a trainer/racer or for multiple races within an event.
