TESTED: Rocky Mountain Slayer Carbon 90 27.5

Dec 2020

Dubbed the ultimate big-mountain bike, the latest iteration of the Rocky Mountain Slayer is an ultra-capable long-travel trail tamer—as long as that trail is sufficiently steep and technical.

Rocky Mountain Slayer Carbon 90 29 on test – we've never felt suspension perform like this!

Jan 2020 · Christoph Bayer

Rocky Mountain have completely redesigned the Slayer. With its super plush rear suspension and downhill-focused geometry, it ended up being one of the favourites of our test crew.

Highs
  • Incredibly sensitive rear suspension

  • Considered and high-quality spec

  • Good pedalling position on the climbs

Lows
  • Front wheel likes to wander

  • Climb switch required for the climbs

  • Aggressor tire on the rear wheel isn’t very versatile
