During a Service of Revalve of your AER48 forks, We can implement a custom OE WP Cone Valve Adaptation System that replaces your mid speed valve. This system uses 100% WP components. The cone spring and rebound valving have been tested with several racers who report very positive feedback about this system. This system allows the rider to dramatically increase the AER air pressure (to allow high fork operation) and still soak up the bumps we all wish we could avoid. This system is $500 if installed during a Revalve. $600 if installed during and service, and (not available0 if the customer wants it installed without a service or revalve package.
