CPR--the latest and most advanced technology in trainer resistance systems

4 to 3,000 Watts! (more resistance range than any other trainer)

                                                      How the CPR works

When you begin to pedal your bicycle, the Friction Plate is resting against the Roller Disk (see top photo-No Gap).  As you speed up, centrifugal force moves 3 steel balls outward, moving the Friction Plate over towards the Friction Pad (see second photo-Gap).  The faster you pedal, the harder the Friction Plate presses against the Friction Pad and the more resistance occurs.  The 6 inch diameter friction pad will never wear out and is guaranteed for life.  The pad is made from a clutch or brake-type material.  The bottom photo shows the Resistance Unit (CPR) disassembled.  

 

Just like riding outdoors, the faster you go, the harder it gets.  This simple design performs better than any other resistance system, for the most realistic ride available.  The CPR System is the quietest system on any trainer with the longest coast-down in the industry.  The large 3 inch Roller provides the smoothest, quietest ride available.  Six angled cooling slots circulate air to cool the unit.  The 1up Trainer has a RC (resistance curve) adjustable system.  The RC System allows the rider to change the resistance curve in the trainer (click on link below).

Larger Roller = less noise and less tire wear.
