Aug 2017 · Josh Patterson

Phenomenally stiff, impeccably controlled, hyper-fast enduro racer that’ll Slash your previous times. Buy if you want maximum speed and accuracy on the roughest, fastest trails

Highs
  • Superbly shaped, jaw-droppingly stiff full-carbon frameset

  • Ultra-sensitive, maximum grip but HD communicative and immaculately poised Fox suspension

  • Mostly excellent wheel, tyre and component pack

Lows
  • TALAS fork adds cost and drag

  • 125mm Bontrager dropper is short and slow
