Product Description
The RockShox Deluxe RE:Aktiv rear shock is a genuine Trek replacement component custom tuned by the Trek Suspension Lab for compatible Trek full-suspension bikes.
This Trek-specific 205 x 57.5mm configuration combines a DebonAir air spring with ultra-responsive RE:Aktiv damping designed to provide efficient pedaling support while reacting quickly to trail impacts for improved traction and control.
External rebound adjustment and three-position compression damping allow the suspension feel to be tuned for changing terrain and riding conditions. The shock uses a trunnion upper mount with Trek-specific lower mounting dimensions, so exact frame compatibility should be confirmed before purchase.
