Our unique Midsize Hyper Crit System is an Industry First 14-Tooth/14-Tooth complete pulley wheel system.  Designed due to customer demand, the Hyper Crit System provides the benefits of a complete system but yet is a bit smaller than it's big brother, our Oversize Hyper Speed System.  Locally produced aerospace grade carbon fiber cages, CNC machined anodized pulley wheels, and coated hybrid ceramic bearings all combine to provide the lowest friction possible along with durability that's unmatched.
All SLF Motion parts are designed, tested, and built by hand in Pawnee, Illinois - USA
