EXT Vecta Shock Easy To Tune. Hard To Beat. The EXT Vecta is a enduro shock built with out compromises. The 3-way adjustable monotube damper design with high and low speed compression and rebound built around the same philosophy that defines every shock EXT racing proudly makes in Ponte di Barbarano, VI. The shock is designed to meet the high standards of modern trail and enduro riders who seek premium suspension characteristics at an attainable price point. Factory-tuned HBC makes compression progressive in the last 15% of stroke, so the shock builds damping force as you approach full travel - no harsh bottom-out, no need to run a stiffer spring to compensate. No risk of cavitation the high turbulent flow valves keep damping forces independent from viscosity and temperature changes. EV2S fluid keeps damping behavior consistent across temperature swings, and a large-volume bladder reservoir pressurized to just 55 PSI maximizes small-bump sensitivity throughout the stroke.
