Ribbon 160 Boost Fork

Offering more adjustability than virtually any fork on the market, the performance-obsessed engineers at MRP created the Ribbon 160 Boost 27.5in Fork to withstand the serious demands of all-mountain thrashing while offering up a customizable feel to your specific riding needs and local trails at hand. Not only did MRP succeed in this ambitious endeavor of creating a fine-tunable fork for discerning riders and suspension geeks, but they did so while keeping the Ribbon competitively lightweight in its all-mountain category at a mere 4.15 pounds. This particular Ribbon fork boasts 160-millimeters of terrain-smoothing travel with BOOST axle spacing for precise tracking of the front wheel over rowdy sections of trail.

Seeing that MRP's local trails in Grand Junction, Colorado are some of the most challenging and diverse in the country, it makes perfect sense that they'd create the Ribbon with 35-millimeter stanchions for reduced torsional flex when you're rallying it over chunky rocks, steep descents, and harsh drops. In fact, the Ribbon is named after an infamous trail in the Grand Junction area, touted as one of the most "unique slab rock trails that's as fast as your bike will permit." This brutal testing ground sets the bar high for the Ribbon's performance, meaning it had to excel on the steepest descents at high speeds, but also pick lines across technical sections with methodical precision.

The Ribbon's new FulFill air spring gives you the fine-tunable feel of independently adjustable positive and negative air chambers, which is ideal for the rider customizing their fork's feel to near-obsessive realms. Whether you need it to be smooth and supple off-the-top or incredibly supportive, the Ribbon is your fork of choice with its independent air chambers. MRP integrated Ramp Control technology into the Ribbon as well, which means you won't have to add or remove volume spacers ever again. This technology gives you 16 position adjustments with the flick of a knob, tuning your fork's behavior to handle harsh hits where you'd normally bottom out. Another cool feature, MRP integrated PSST valves to bleed out the lowers when drastic changes in elevation and temperature mess with the operation and feel of your fork.

Perhaps its most notable design feature, the Ribbon features a "twin-tube" style damper that's seldom seen on forks, due to engineering complexity. MRP calls this the EssenTTial damper, which uses a low-pressure internal floating piston (IFP) instead of a bladder to eliminate stiction while improving reliability and consistency over the open bath and mono-tube dampers found on the competition. When it's time to service the fork, the cassette-tool interface along the top cap and external bleed ports make it a relatively quick and easy endeavor.

Ultimate Adjustability & Performance

I've put it through the wringer

The Ribbon offers more adjustability and performance than any other fork on the market while still coming in at a relatively light 4.2 lbs for the 29 version. With the FullFill negative/positive air springs you can dial in the amount of suppleness you like, using less air in the negative chamber to make it firm off the top or more air to maximize small bump compliance. Then with the Ramp Control you can dial in the progressivity, so you can have a fork that's super supple off the top but resists bottoming out on big hits, or go the other way and make it firm for pedaling, but able to use full travel on more moderately sized trail features. Being able to adjust the ramp without tools is invaluable too, as you can adjust mid-ride if you find yourself hitting larger than normal features, or if you find yourself not using all the travel; that's something you can't do with tokens. Then there's the twin-tube damper with low speed compression adjustment that ends up using less pressure than other, simpler designs for greater control and support throughout the stroke. Oh yeah, don't forget that the travel is adjustable from 120mm - 160mm for the 29er version and 140mm - 170mm for the 27.5. It took a couple rides for me to get this fork dialed, but now I can't believe how supple yet supportive it is and how well it still manages to handle big hits. Stiffness is more than adequate, and the outcast arch design looks cool and doesn't fill with mud like every other fork. It also has pressure relief valves for bleeding off pressure in the lowers that develops from heat or elevation changes. To be honest I've yet to use them and feel a difference, mainly because the fork just always feels so damn good. But I've definitely encountered this problem with other forks, so it's good to know it's there. Bottom line, this is a fork that brings the competition to the big guys in the suspension market, and ultimately surpasses them with a product that has no drawbacks and has a competitive weight and price to boot.
