ROCKY MOUNTAIN INSTINCT ALLOY 70 (2018)
The Rocky Mountain Instinct is our most popular trail bike. We have the confidence in being able to recommend the bike because no matter what you’re skill level or where you ride, the Instinct Alloy 70 should be on your shortlist of trail bikes. We’ll explain why.
THE INSTINCT’S FRAME AND FEATURES
Rocky invest a huge amount of time and resources into ensuring that their aluminium frames are one of the best. It features the usual high-end finishes such as internal cable routing, clean, strong welds and a perfect cable entry and exit ports.
Much as been improved with new generation Instinct. Rocky has removed all bushings and replaced them with sealed bearings from the best in the biz - Enduro Bearings.
All pivots locations have them. As an extra step, the lower shock mount uses a double row of sealed bearings. Eliminating bushings and using pivots has significantly improved the small bump compliance of the Instinct. Bearings have improved the way the rear wheel tracks over bumps and impact. At the rear stays, the pivots are concealed. It’s not something we commonly see but definitely makes the frame a little bit more special.
The Instinct Alloy 70 operates on 140mm of rear wheel travel. The boffins at Rocky have made every millimetre of that travel work flawlessly. Sealed bearings and the new Float DPS rear shock handle the small bump compliance. Better mid-travel support helps the bike stay dynamically stable in the corners. And the suspension kinematics (and Ride 9 position, more on this later) are tuned to naturally deliver progression through the end stroke.
WHAT ON EARTH IS RIDE 9? IS IT GOOD?
Ride 9 is Rocky’s unique way of allowing riders to change the Instinct Alloy’s geometry in 9 different ways. And yes, it’s very, very good. Here’s why.
Most manufacturers produce bikes with a fixed geometry. One set of angles that you’re locked into. No adjustments, just set and forget. Sounds OK right? Well, not always.
You see, when you’re riding a bike with a fixed geometry, the manufacturer assumes stuff. And when you don’t match those assumptions, it’s you that has to make compromises. Either compromising on the bike’s climbing efficiency or descending ability. You can’t have both, something has to give.
Not so with the Instinct’s Ride 9.
Having Ride 9 is kind of like having 3 bikes in one. There is so much scope for adjustment that you can tailor the Instinct to suit any terrain; gravity or cross country. There are 3 modes that are the key zones for Ride 9. These are:
When you know the descent is going to be scary and you’re crazy enough to attempt it anyway. In Slack, the Instinct's centre of gravity is at its lowest point. All the angles slacken out and deliver a ride that is incredibly grounded and stable. Perfect for when lots of speed and gravity are involved.
It also changes the behaviour of the rear shock and makes adds progression to its damping. This means you don’t bottom and use all your travel landing jumps and drop-offs. It also gives the bike a bottomless feel like you’ve got way more than 130mm of travel under you.
This is the most average position in the spectrum. It falls directly between the Slack and Steep modes. Use this for when the trails are equally steep, up and down.
Use this mode if you want to make pedalling and climbing up stuff easy as possible. It raises the centre of gravity of the Instinct and steepens all the important angles putting you in the most efficient climbing position. Unlike the Slack mode, Steep makes the rear shock more linear. A linear shock behaviour results in the best climbing traction.
THE OTHER STUFF
The Instinct Alloy 70 build features a lot of high-end components.
FOX PERFORMANCE ELITE
Fox’s Performance Elite suspension is second tier, one below the Factory. It’s like 99% of the performance and quality though. The damping is controlled by a sophisticated damper called FIT4 (Fox Isolated Technology, Gen 4). FIT dampers are closed bath systems which means they separate the oil and the air from mixing together. Once this happens the suspension fork starts to feel very harsh.
Fox’s Performance Elite suspension can be tailored to any terrain. There are a few key adjustments including air pressure, rebound and a 3 stage compression circuit (soft, medium and lockout).
We’ll give you a complete rundown on setup and maintenance in store. Speaking of maintenance, Fox recommends getting a full service done every 125 hours or annually - whichever comes first.
SRAM GX EAGLE
Needs no introduction. The massive 500% gear range and the level of engineering that's gone into manufacturing the drive train parts deliver the smoothest gears changes. No exaggeration, it’s properly good.
