CUSTOM TUNE ON THE TRAIL
Undoubtedly, convenience is one of the biggest benefits of the ramp control cartridge versus internally accessed volume adjustment components. Internally accessed spacers aren’t that friendly to on-trail experimentation and tuning – requiring bulky tools and a clean environment to utilise. 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.
A BETTER WAY TO TUNE
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 volume of the cartridge itself, the Ramp Control upgrade effects 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 sizeable drop or ploughing through a rock garden. Without Ramp Control, your forks 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 Ramp Control adjustment.
NO MORE COMPROMISES, TUNE TO THE TRAIL AT HAND
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 ad 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 endure fans tasked with practicing and racing multiple, varying stages.

Fox 36, Version D
This new model goes beyond our previous offerings and includes parts
to convert the stock air-spring into an independent positive and negative chamber arrangement similar to the Fulfill™ spring found in our Ribbon and 2017 Stage forks. Once installed, you can now vary the pressures in your two chambers; increasing your negative spring rate to improve small bump sensitivity (a common complaint with the stock spring). This, in addition to the control you have over bottom-out and ending-stroke performance, gives you a radically more sophisticated air-spring that’s incredibly straightforward to tune and adjust!
...will fit 2015-2017 Fox 36 Float forks with the FIT 4, RC2, and Grip dampers. Recommended for 140-180mm 29”, 27.5+, and 27.5” forks.
Fox 36, Version F
Version F is a cartridge-only kit suitable for 2018 Fox 36 forks of all travel and wheelsize options. A revised air-spring design in Fox's latest 36 makes the Fulfill™ spring conversion included in Ramp Control Upgrade Version D incompatible.
...will fit 2018 and newer Fox 36 Float forks with the FIT 4, RC2, and Grip dampers. Recommended for 140-180mm 29”, 27.5+, and 27.5” forks.
Fox 40, Version E
...will fit 2016 and newer Fox 40 Float Factory and Performance Elite forks.
Fox 38, Version G
...will fit 2020 and newer Fox 38 Float Factory and Performance Elite forks.
X-Fusion, Type A
...will fit 2013 and newer X-Fusion 34mm forks of all travel options. 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. Adjustments add between 1 (fully open) to 4 tokens worth of adjustment (Fully closed). 16 clicks give roughly 20% of one token per click in Rock Shox forks.
