Rocky Mountain Slayer 2017

The all-mountain legend returns...

Designed to lay waste to the world’s roughest trails, the rocky mountain Slayer is back for 2017 as an all-carbon weapon handling the most aggressive Enduro World Series tracks to bike park laps and big mountain lines. All Killer, no Filler.

 

rocky mountain slayer – the review

With its downhill-bike capability, 170mm fork and 165mm of rear travel this all-new Rocky Mountain Slayer goes head to head with our favourite enduro bikes such as the Radon Swoop, YT Capra and the revised Commencal Meta AM V4.2. Some tough competition with this bunch, but Rocky Mountain promise us that the Slayer’s pedalling responsiveness is matched with an uncanny ability to find and hold speed in rugged terrain. Rocky Mountain have stuck with what they feel is the right size for the job in hand and developed the Slayer to roll on 27.5″ wheels rather than giving a choice, as with the Specialized Enduro, or following Trek’s route with the almighty 29″ only Slash.

Rocky Mountain are based in Vancouver, Canada, so hard-hitting yet durable bikes have always been on their agenda. A short pedal from the Mount Seymour trailhead, Rocky Mountain’s Development Centre is nestled at the foot of Vancouver’s North Shore Mountains and it’s here that the engineers take full advantage of their prototype frame shop and testing facility when developing new designs. The first Slayer model was launched over fifteen years ago at a time when efficient ‘platform damping’ rear shocks were new and enabling trail bikes to gain travel and ability yet stay capable and surefooted whether on slow technical drops, or fast high speed descents. At that time, the 120mm travel Slayer bridged the gap between skinny XC bikes and over built freeride machines.

For 2017 the Slayer now sits in the Rocky Mountain range above the 160/150mm Altitude and below the Maiden DH bike.

“When we decided to bring the Slayer back, we knew it needed the crush-everything-in-its-path attitude of the previous generation while keeping the agility and efficiency that made it a favourite among aggressive trail riders.” Rocky Mountain.

 

FRAME DESIGN

Rocky Mountain use their Smoothwall™ carbon for the new Slayer frame. This uses one of the world’s most sophisticated carbon processes to build frames with industry leading stiffness-to-weight, ride quality, and durability. By using rigid internal molds, they are able to perfect the shape of the internal features and eliminate excess materials. Different types of carbon is used in specific frame areas to maximize stiffness and impact resistance while minimizing overall weight.

The updated geometry retains a fairly steep seat-tube angle, while the reach has been extended and the head-tube angle has been slackened.

Rocky have kept the BB drop neutral and the rear chainstay length remains relatively short to improve cornering in the tight stuff. This new design has the seat-tube lengths kept short to make room for the next generation of longer dropper posts, a good move as we are seeing this as an issue on some recent frame designs.

The Ride-4™ adjustability system was chosen for the Rocky Mountain Slayer in order to provide precise geometry adjustments while leaving the suspension curve virtually unaffected. The head-tube and seat-tube angles can be changed by just over a degree, and the bottom-bracket can be raised or lowered by 7.5mm. This allows racers to adapt their geometry from track-to-track while keeping shock tuning predictable and simple. Not every rider has the same taste in bike set-up and this feature lets you sweat the details without any aftermarket component additions.

A Size Specific Tune™ on the shocks ensures that riders of all sizes get the right balance of small-bump compliance, mid-stroke support, and end-stroke progressiveness. Their design team does custom shock tunes based on real world field testing, and adjusts each tune for every specific frame size, from S to XL.

Internal cable routing and ISCG 05 tabs are standard on all models.

“I’m super fired up that the Slayer is back. A few things really stood out to me through the development process—it pedals incredibly well, carries a ton of speed, and that extra bit of travel is awesome when you really want to rally! I see myself spending a ton of time on this bike.”  Thomas Vanderham, Rocky Mountain team rider.
