Total tuning range (strictly in terms of ending-stroke support) is roughly equivalent to 1-4 tokens. Thus fully open, the Ramp Control cartridge reduces spring volume similar to one token. In its strongest setting, and under a high-speed compression, the ending-stroke support will be similar to a spring with its volume reduced by four tokens.

BENEFITS:

Inarguably, convenience is one of the biggest benefits of the Ramp Control cartridge versus internally-accessed volume adjustment components. Internally-accessed 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 internally-accessed spacers would necessitate a trial and error approach - several rides followed by garage or shop sessions - to get to the same point.

The volume adjustment spacers used by competing brands 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 effects only the ending stoke 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.

Unless you ride just one trail, the air-spring volume you’ve so carefully tuned with internally-accessed volume spacers is probably not ideal for all your adventures. A trip to the bike park might reveal, for example, that more support would be welcomed when the features and drops get bigger and trails get steeper than those found on your local go-to. If you have extra spacers and the necessary tools on hand, and don’t mind burning time that could otherwise be spent riding the lift-accessed terrain you just paid for, you could get the needed support. Or, in just seconds, you could add more Ramp Control and keep the good times going. Whether it’s a new-school flow trail or near vertical DH course, Ramp Control gives you immediate control of the terrain at hand - of particular benefit to time-crunched enduro fans tasked with practicing and racing multiple, varying stages.
