First Look: MRP Ribbon Forks

by
August 4, 2017

Up until a couple of seasons ago, your options for a long travel suspension fork were largely confined to just two brands. Or at least from a performance and serviceability perspective anyway.

There’s been a recent explosion in the number of suspension offerings on the market however, and now riders have a load of choices to contend with. In the long travel trail bike arena, you’ve got the likes of the Manitou Mattoc, Formula Selva, DVO Diamond, Ohlins RXF 36, Cane Creek Helm, X-Fusion McQueen, and BOS Deville jumping into the pool with the more mainstream options like the RockShox Pike and Fox 36.

In addition to those forks (and others), there’s yet another option on the market, which we first came across at last year’s Eurobike show at the MRP booth. Modelled on the existing MRP Stage fork, the new Ribbon fork brings fourth a Boost-specific chassis along with a few other improvements including the Ramp Control cartridge, and has made quite the splash doing so. We were teased again with the Ribbon fork again at Core Bike earlier this year, but now after months of waiting for production, we’ve finally got one in to test.

It’s taken a while, but now MRP’s Ribbon fork is available in the UK.

Our goal in designing the 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 we had to reimagine elements like casting design, reconfigure damper architecture, and completely retarget performance goals. The result is not just the best fork we’ve ever produced, it’s the new industry benchmark” – From MRP.

Chunky magnesium lowers and QR15 lowers.

Equipped with 35mm diameter stanchions and travel up to 170mm, the MRP Ribbon is a long travel trail fork that comes loaded to the hilt with adjustments and features. It’s available in both 27.5in and 29in versions, with both forks being built around Boost-specific 110x15mm thru-axle lowers. The Ribbon fork will accept up to a 2.6in wide tyre for the new plus-minus brigade, though if you want to go proper plus, the 29er Ribbon will fit up to a 27.5×3.0in wide tyre.

It’s like a regular arch, but flipped around to put the mud-catching bits on the front – away from the mud.

The lowers are crafted from magnesium, and use a rather unusual arch that puts the hollowed-out section on the front side of the arch. It isn’t a Reverse Arch like you’ll find on a Manitou or DT Swiss fork, but rather a conventional arch that has been flipped around. The reason? So you don’t end up with mud collecting in those hollowed-out pockets. It also gives the Ribbon a very unique look too. Personally, we’d like to see some kind of bolt-on plate to cover up the hollow section completely. Maybe with some sweet anodized colours?

Press the nipples to release the pressure.

Just below the wiper seals on the backside of the fork lowers, you’ll find two little bleed nipples. These are pressure release valves, or as MRP likes to call it, the ‘PSST’ buttons. Just like you’d find on a downhill fork like the Fox 40, these little valves are designed to release air pressure that’s accumulated inside the fork lowers from changes in altitude or temperature. For those who frequent alpine terrain, this in theory should provide more consistent performance when you’re packing in run after run via the chairlift.

Subtle external bulges can be found on the lowers around the area that supports the bushings inside.

The Ribbon forks are Boost-only. However, MRP does make a kit that’ll allow your 100x15mm DT Swiss or Stans NoTubes front hub to fit into 110x15mm Boost dropouts.

The 15mm alloy thru-axle uses a very Fox-like QR15 lever. Which is no bad thing really.

Adjustable low-speed compression damping via the black dial on the top of the R/H fork leg.

Inside the right-hand leg of the Ribbon fork you’ll find all the damping gubbins. MRP has chosen not to go with an expandable bladder system like the Fox FIT or RockShox Charger damper, but rather a low pressure IFP is used to push oil back into the damper upon the return stroke. Speaking of damping oil, MRP has some pretty big service intervals on the Ribbon fork, with the US company stating that you can get 200 hours of ride time out of the Ribbon before the damping oil needs to be changed.

Red rebound adjuster sits at the base of the right-hand fork leg, along with a guide for the number of clicks in all of the external adjuster dials.

The orange dial adjusts the Ramp Control for fine-tuning bottom-out resistance.

The Ribbon’s air spring offers no fewer than three different adjustments. There’s a positive chamber, a negative chamber, and the Ramp Control cartridge that allows you to tune the bottom-out resistance of the fork. In general, MRP recommends running the negative spring pressure around 10% higher than the positive chamber, though ultimately you can tune and adjust to your hearts content to get the right feel you’re after.

Confirmed weight with an uncut full-length steerer is 1924 grams – almost dead on the claimed weight.

Each Ribbon is built to order by MRP at the requested travel setting, and with your choice of decals.

So the question remains; does MRP have what it takes to knock the RockShox Pike/Lyrik and Fox 34/36s of the world? We’re sure keen to find out, and if you are too, make sure you stay tuned for our full review of this long travel 29er fork.
