Product details
Product Description
The FOX Performance RE:aktiv Thru Shaft rear shock is a genuine Trek replacement component custom tuned by the Trek Suspension Lab for compatible Trek Fuel EX suspension platforms.
This Trek-specific shock features a 210mm eye-to-eye length, 52.5mm stroke, EVOL large-volume air sleeve, and an ultra-responsive RE:aktiv damper with FOX Thru Shaft technology. The design provides efficient pedaling support while reacting quickly to trail impacts for improved traction, control, and suspension consistency.
External rebound adjustment and a three-position damper allow the rider to tune the shock for changing terrain and riding conditions. This specialized shock uses Trek-specific trunnion mounting dimensions, so exact frame compatibility should be confirmed before purchase.
