Aftermarket version of the Ramp Control system used in the Ribbon.MRP's Ramp Control cartridges are designed to fit RockShox forks with 35mm stanchions. This upgrade threads into the air spring on Pike, Yari, Lyrik and Boxxer forks and allows the user to dial in the amount of progression in the fork without resorting to adding or subtracting RockShox's bottomless tokens.
