The Rocky Mountain Slayer is back! Back at its initial launch in 2011, people were already impatiently wondering about a carbon-framed version and now the wait is finally over as Rocky Mountain launch a brand new Slayer capable of tearing down the hardest trails on Earth – and yes, it has a carbon frame! Keep reading to find out what else is new.

The frame of the Rocky Mountain Slayer MSL
The new Slayer MSL is built around a stylish carbon frame with 165 mm of travel. In true Rocky Mountain style, the Slayer also boasts geometry adjustment in the form of the RIDE4 system, which it has borrowed from the Maiden downhill bike.



Kitted out a 148 mm Boost rear hub standard, the Slayer employs a design with a one-sided fastening between the chainstays and seatstays to ensure bags of space for your heels. The frame uses high quality MAX Type Enduro ball bearings. Conceived for 2.5″ wide 27.5″ tires, the frame is also compatible with 26+. And yes, you read that correctly: 26+!






An overview of the frame:
- SMOOTHWALL full carbon frame
- RIDE-4 system permits geometry adjustment
- all frame sizes are capable of mounting a bottle cage mount
- Well thought-through: Di2 and dropper seatpost both compatible
- Bearings with ‘MAX Type Enduro’ sealed industrial bearings und simplified hardware, PIPELOCK bearings rocker link pivot
- one-sided fastening of the chainstays and seatstays allows a narrower rear end. Even with the Boost hubs, your heels have sufficient space.

The suspension on the Rocky Mountain Slayer MSL
When it came to designing the Slayer, Rocky Mountain settled on a four-pivot rear that is defiantly anti-squat and reputed to be exceptionally efficient. The 165 mm of rear travel comes courtesy of a metric rear shock measuring 230 x 65 mm. There’s an extra bearing in the top of the rear shock mount that is designed to guarantee more responsiveness.

The top-end Slayer 790MSL makes good use of a FOX X2 rear shock, while the other models rely on a RockShox Super Deluxe. Their suspension curves are purported to offer great sag support as well as stability in the mid-stroke and moderate end progression.

Our first impression of the Rocky Mountain Slayer MSL
What a comeback! Even on paper, we were stoked to see just how rapid and potent the Rocky Mountain Slayer appeared! The narrow chainstays, extra ball bearings in the rear shock mount, integrated chainguide and the Wide Trail tires are concepts that are testament to good, well thought-out design from the Canadians. But the jury is still out on their decision to bring yet another wheelsize, the 26+, into the already pretty stacked equation. One thing is certain though: rolling on 27.5″ tires, the new Slayer is a hard-hitting rig to take on the world’s gnarliest trails. We’re biting at the teeth to get our hands on this bike for a proper test, as we’re already sold on the concept. It’s brilliant to see that all the models come in the same two colourways: after all, we think bikes should be defined more by their frame and less by their components.
