The new Marin Mount Vision all-mountain trail bike brings the model back after taking it out of the line in 2017. For 2019, it’s back with a vengeance, using a new variant of the NAILD R3act-2Play suspension platform on the longer travel Wolf Ridge. With the Wolf Ridge, they wanted to showcase just how versatile that platform could be by putting it on a bike that works for everything from XC to enduro on a 160mm 29er mountain bike.

With this new Mount Vision, they wanted to really focus in on a more category-specific bike tuned specifically for all mountain and enduro. Goals included a more specific geometry, maximum dropper post length compatibility, and “playful but poised” handling. Here’s how they did it…

The first step was dropping down to 27.5″ wheels. They wanted the quicker, more playful nature this wheel size delivers, so there’s no 29er option, but it’ll fit up to 27.5×2.6″ tires. While shorter options are available these days, they stuck with a 44mm fork offset to maintain high speed stability since the bike has a shorter rear-center measurement (read as “it keeps the wheelbase from being too short”).

Next up was the geometry, which does all the right things…longer, lower, slacker with a short stem. What’s interesting is that there’s actually a minimum recommended tire size of 2.35″. The BB is really low, so anything smaller than that will simply put the bike too low and really increase the likelihood of pedal strikes. We’ll talk about this more in our first ride review, coming soon.

The frame is UD monocoque carbon with 150mm travel front and rear with two different suspension kinematics for S/M and L/XL. Let’s start there: The R3EACT – 2 PLAY suspension is meant to keep the rear wheel planted on the ground by removing compression damping from the equation (the bikes get Fox’s extra-light tune that’s about a 60% reduction compared to what’s found on most bikes), yet it won’t bob through the travel thanks to the unique anti-squat and anti-rise characteristics of the system.

They added an upper swing link, which is injection molded carbon fiber, which did a couple things. First, it changes the suspension’s curve slightly, giving it a “poppy” feel that makes it easier to pop the bike off jumps and just be a little more playful than, say, something that feels like a downhill bike. Second, compared to the Wolf Ridge’s design, it makes room for a water bottle cage on the downtube. And for Large and XL frames there are two sets of bottle bosses on the downtube…both inside the front triangle!

They put thin steel shields on the bearings there, too, to protect them from high pressure bike washings and general crud.

Shown above and below is the slider, which keeps the rear swing arm moving in the right path. While it does seem like a high-wear area, they use the same o-ring and seal system as motocross bikes, so they say it’ll hold up to MTB use just fine.

One of the design constraints of this suspension system is the longer, more forward-jutting bottom bracket section. To protect it, they added a glass-reinforced nylon moto-style skid plate that’s bolted onto the bottom of the frame with thick foam tape between the two as extra impact absorption. It has drain holes matched to the holes in the frame, too.

  1. I wont’ say anything about relative cost to competitors, but in terms of absolute costs/inflation, bikes seem to be getting insanely expensive.

    Nice bike, but I think it’ll leave this long legged, short torso person with too slack of an effective ST angle compared to other offerings. These insanely slack actual ST angles only work if your seat height is around handlebar height. Worth trying though.

    • Why does this work well if “seat height is around handlebar height”? I’ve heard about the slack seat tube on this bike also but I’m not really understanding where it would be good and where bad.

      • Effective ST angles are almost always calculated with the seatpost top height equal to the listed stack measurement.

        Given my long legs for my height, I run BB to saddle heights that put the seat way above the stack measurements on most bikes. Geometry being what it is, my effective ST becomes slacker than most geometry charts show, and the slacker the actual ST angle, the more effect it has. Most times one can get away with a saddle adjustment, but there are limits to that.

        For a clear visual, look at the geometry chart in this article. The intersection of the dotted line on the actual seat tube and line “G” is where virtual ST angle (“E”) is calculated. As you extend the seat post upward, that intersection point moves backward, reducing effective ST angle.

        There are “conservative” geometry bikes that are actually more progressive for me than some “aggressive” geometry bikes if the latter have low stack heights and very slack actual ST angles. Most people probably feel this in a demo, but its easily calculated and can provide insight into bike fit and frame size choice.

        • Well, you clearly don’t matter enough to worry about for big bike companies. That is why smaller companies that do custom geometry work better for folks like yourself. Unfortunately it comes at a cost penalty.

          I agree though, older bike geometry didn’t matter as much for people of your proportions. It was terrible for people with a very long torso though.

  2. I thought I was seeing a nightmare of a single pivot. After seeing the pricing, I must be on something, but there are crazy

  3. There’s going to be comments on how this suspension won’t do what they want it to because of antisquat anti Rises-mid stroke-whatever. Then there’s the rider that knows this is the best design ever,but can’t get over the looks so they still ride their ( insert California\colorado based frame manufacturer.) I fall into the group that knows this setup rocks, but …it’s…a …Marin
