Overview
The Rocky Mountain Slayer is the brand’s longest-travel, most aggressive full-suspension mountain bike — a freeride-focused machine with 180mm of travel front and rear. Built for the steepest, roughest terrain and gravity-oriented riding, the Slayer features a SMOOTHWALL carbon (or FORM aluminum) frame, the RIDE-4 adjustable geometry system, and a Fox DHX2 coil shock on select builds. The Slayer uses a mixed-wheel (MX) setup on SM and MD sizes (29″ front / 27.5″ rear) and full 29″ on LG and XL.

The Slayer’s geometry in the neutral RIDE-4 position is purpose-built for gravity riding: a 63.0° head angle, 77.5° seat tube angle, and reach spanning 430mm (SM) to 510mm (XL). The RIDE-4 system offers the slackest configuration at 62.5°, making it one of the most gravity-oriented trail bikes available. Chainstay length is approximately 439mm across all sizes with fine adjustment via the two-position axle dropout. The BB drop of 22mm (on 29″ sizes) keeps the rider’s weight low and centered. With Maxxis Double Down tires and CushCore inserts included as standard on most builds, the Slayer is ready for the roughest terrain right out of the box.

Geometry Analysis
The Slayer’s 63.0° head angle in neutral position is among the slackest in the enduro/freeride category, and the RIDE-4 system can push it to an extreme 62.5° in the slackest setting. This is gravity-bike territory, designed to keep the front wheel planted and stable on the steepest descents. The 77.5° STA is surprisingly steep for such a gravity-focused bike, reflecting Rocky Mountain’s commitment to making the Slayer pedal-capable despite its freeride intent. Reach follows a clean 25mm-per-size progression, reaching a massive 510mm on the XL. The SM and MD sizes run MX wheels (29/27.5), which lowers the BB and creates a more maneuverable rear end. LG and XL switch to full 29″ with a deeper 22mm BB drop. The consistent ~439mm chainstays are moderate for this travel class, providing a balance between stability and agility.
Ride Characteristics
The Slayer is a gravity-first machine that excels when the terrain gets steep, rough, and wild. The 180mm of coil-sprung travel (on DHX2-equipped builds) provides a bottomless, plush feel that devours the biggest hits and most sustained rough sections. The slack geometry and long wheelbase create immense stability at speed — this is a bike that encourages you to go faster and hit bigger features than you normally would. Drop-offs, jumps, and rough chutes are the Slayer’s natural habitat. The Penalty Box downtube storage is a nice touch for carrying tools on big days. On climbs, the Slayer is heavier and less efficient than the Altitude, but the steep STA and coil shock’s small bump sensitivity keep it more manageable than you might expect. That said, the Slayer is not a bike you choose for its climbing prowess — it’s a pure descender that happens to be able to pedal back up.

What’s New vs Previous Generation
The current Slayer platform was introduced in 2023 as a comprehensive redesign, and the 2024 model continues with spec-level updates. Key innovations from the redesign include MX (mixed-wheel) compatibility on SM-MD sizes with full 29″ on LG-XL, the RIDE-4 adjustable geometry system, Penalty Box downtube storage (carbon models), and a frame designed around modern coil shocks. The 2024 updates focus on build-level refinements including updated suspension tunes and component specifications.
Who Should Consider This Bike
The Slayer is purpose-built for riders who prioritize gravity-oriented riding above everything else. If you shuttle laps, ride bike parks, tackle the steepest and roughest terrain available, or simply want the most capable descending bike Rocky Mountain makes, the Slayer delivers. It’s also an excellent choice for coastal BC riders who regularly face steep, technical, root-laden terrain. If you need to pedal significant distances or want a bike that’s versatile across terrain types, the Altitude is the better choice.
Comparable Models
The Slayer competes with the Santa Cruz Nomad (170/170mm), Specialized Enduro (170/180mm), Norco Shore (200/190mm), YT Tues (downhill), and Trek Session (downhill). At 180/180mm, the Slayer sits between traditional enduro bikes and dedicated downhill rigs. The Nomad and Enduro are the closest competitors with similar gravity-trail intentions. The Norco Shore is one of the few bikes with even more travel. The Slayer’s coil shock standard and RIDE-4 adjustability differentiate it from the pack.

Frequently Asked Questions
Is the Rocky Mountain Slayer a downhill bike?
The Slayer occupies the space between enduro and downhill. With 180mm of travel, a 63° head angle (adjustable to 62.5°), and coil shock compatibility, it handles terrain that would overwhelm most enduro bikes. However, it still has pedal-friendly features like a steep STA and dropper post, making it more versatile than a pure DH bike.
What wheel size does the Slayer use?
The Slayer uses a mixed-wheel (MX) setup on SM and MD sizes with a 29-inch front and 27.5-inch rear wheel. LG and XL sizes run full 29-inch wheels front and rear. This size-specific approach optimizes handling proportions for different rider heights.
Does the Slayer come with a coil shock?
Select builds (like the C70) come with a Fox DHX2 coil shock standard, with size-specific spring rates (400-550 lbs). Other builds offer air shocks. The frame is compatible with both coil and air shocks, so riders can switch to suit their preferences.
How does the Slayer compare to the Altitude?
The Slayer (180/180mm, 63° HA) is the gravity/freeride option with more travel and a slacker head angle. The Altitude (160/170mm, 63.5° HA) is the enduro race bike with the LC2R suspension, lighter weight, and better climbing efficiency. Choose the Slayer for maximum descending capability; choose the Altitude for balanced enduro performance.
Can the Slayer be used for enduro racing?
Yes, though it’s heavier and less pedal-efficient than purpose-built enduro race bikes like the Altitude. The Slayer excels in enduro races with steep, technical stages where its additional travel and stability are advantageous. For races with significant pedaling between stages, the Altitude would be faster overall.
