Inarguably, convenience is one of the biggest benefits of the Ramp Control cartridge versus volume spacers. Volume spacers aren’t friendly to on-trail experimentation and tuning - requiring bulky tools and a clean environment to utilize. With Ramp Control, experimentation is so simple it’s encouraged! The powerful range of Ramp Control is harnessed through a simple 16-position knob with clearly defined detents. That enables you to arrive at your base setting in just one ride on a familiar trail, whereas internal spacers would necessitate a trial-and-error approach - several rides followed by garage or shop sessions - to get to the same point.


Tokens and volume spacers aren’t friendly to on-trail experimentation and tuning. Ramp Control provides precise control over air spring support via a 16-position knob with crisp, clear detents. In seconds, you can perfectly dial-in your fork for ANY trail , on-the-fly. 


Progressive, volume-reduced air springs can worsen ride quality and buck you off line in slow, technical riding. A benefit of its speed-sensitive nature, Ramp Control gives you additional spring support only when you’d WANT it. 


Volume-tuning requires changes to air-pressure and damper settings, meaning one change necessitates several others. Ramp Control unlocks exacting control of spring support independent of these other settings. 


Volume adjustment spacers change the shape of the air-spring’s curve throughout the entire travel range, regardless of velocity. Aside from the slight change resulting from the volume of the cartridge itself, the Ramp Control upgrade affects only the ending stroke spring curve - as its damping effect is velocity-dependent. This portion of the curve represents intense, sharp hits and big events, like landing a sizable drop or plowing through a rock garden. Without Ramp Control, your fork’s behavior in these circumstances has been compromised by your desired feel elsewhere in the stroke. With Ramp Control, you can tune the general feel of your fork through its air-pressure and damper settings, and isolate big-hit performance and bottom-out with the Ramp Control adjustment.
