Versatile Enduro fork with large adjustment range!
The goal in designing the MRP Ribbon was seemingly impossible: Building on the success of the heralded Stage, create a fork with higher performance, more adjustability, more features, all at a significantly lower weight. Those incredible demands meant the developers had to re-imagine elements like casting design, reconfigure damper architecture, and completely retarget performance goals. The result is not just the best fork MRP has ever produced, it is the new industry benchmark.

The Ribbon's stout 35mm stanchions slide effortlessly on anti-friction treated wiper seals and slotted Norglide bushings. Also the appearance of the Ribbon stands out from the crowd by the Outcast™ arch design with forward-facing weight reliefs to mitigate mud build up - as mud and dirt are mainly thrown against the arch from behind. The chassis stiffness is supported by a proprietary through-axle called QtapeR with Boost spacing. On the lever side the axle has a conical tapered washer, and there is also tapering at the female threaded dropout. The idea is that this helps prevent lower leg twist, which can bind with the uppers.
The FullFill™ air-spring system with independently adjustable positive and negative air-chambers allows for greater tunability. The advanced spring is paired with the EssenTTial™ twin-tube, bladder-free damper that is utilizing a low-pressure IFP. Last but not least the developers has add PSST™ pressure-relief valves that quickly and easily bleed off excess pressure in the lowers caused by elevation and temperature changes.

Ramp Control
The Ramp Control unit is located within the air spring assembly, and adjusted via a 16-position knob on the top of the fork leg. Ramp Control gives you the ability to adjust, on-the-fly, the air spring's ending-stroke curve. Part high-speed compression damping, part bottom-out control, Ramp Control is completely independent of your damper or air spring pressure settings. All MRP forks feature super-supple small-bump compliance, but with Ramp Control you can set your fork up to be super plush but still resist bottoming. Cadillac-plushness not your thing? Dial back the Ramp Control and up your pressure to enjoy a more linear fork that rides high but uses every inch of travel effectively.

Compression
As you turn the dial clockwise, you are adding compression damping or slowing the forks compression stroke. It is an adjustment that is subtle, and often overlooked, but can make a big difference in how your fork performs. Aggressive riders tend to like more compression damping because it provides a firmer, more positive feel. Comfort oriented, less aggressive riders tend to like less because it allows more small bump sensitivity. Do not confuse compression damping with spring rate (air pressure). They are very different adjustments, and while adding compression damping may make the fork feel "stiffer", it is not changing the spring rate.
In the eighth, final position of the compression adjustment range MRP's patented magnetic valving provides a highly-damped, supported feel perfect for smooth trails, road stretches and transfer stages. Should you encounter any rough patches however, the magnetic valving will "blow-off" and allow the fork to cycle and your front wheel to track.

QtapeR
QtapeR combines the simple functionality of a quick-release with the stiffness, control, and security of a through-axle.
The "taper" in QtapeR comes from the tapered, conical interface found in the dropouts that mate to the wedges found on the axle mechanism. In contrast to quick-release through-axles that simply pinch the hub between the dropouts, the QtapeR axle's wedges drive into the conical dropouts and expand with the closure of the axle cam - effectively mating the axle, dropout, and hub in harmony. For those familiar with pinch-bolt through axles, the QtapeR works essentially the same way - but with no tools needed.

ChocoLUXE Internals - ChocoLUXE is a proprietary material utilized in our air-spring sealhead, damper plug, damper seal, damper IFP, and damper support.

It’s highly dimensionally stable, meaning that parts made from it are more consistent overall and less susceptible to changing with exposure to temperature swings or humidity.

It is also extremely low friction.

Norglide Bushings - Norglide Bushings from Saint Gobain are metal-reinforced, self-lubricating bushings with a layer of a low friction PTFE compound. They’re exceptionally smooth and durable.
