RockShox Deluxe RE:Aktiv Thru Shaft 230x57.5mm Rear Shock for Trek Bikes

Product Description
The RockShox Deluxe RE:Aktiv Thru Shaft rear shock is a genuine Trek replacement component custom tuned by the Trek Suspension Lab for compatible Trek full-suspension bikes.

This Trek-specific 230 x 57.5mm shock combines a Solo Air spring with Trek’s ultra-responsive RE:Aktiv Thru Shaft damping system. The design is engineered to provide efficient pedaling support while reacting quickly to trail impacts for improved traction, control, and suspension consistency.

External rebound adjustment and three-position compression damping allow the rider to adjust suspension behavior for changing terrain. The shock uses a trunnion upper mount and a Trek-specific offset yoke lower mount, making exact frame compatibility especially important.
