Standard equipment in all Wren suspension forks. Real-world tested down to -27°F (so far), the Wren All-Weather damper is the only damper you need to ride in all temperatures. Wren dampers are sealed cartridge unit that prevents contamination and needs no servicing. The sealed unit uses a flexible bladder to keep the oil under pressure at all times greatly reducing the effects of cavitation at high damper speeds. Wren dampers have both compression and rebound circuits and provide a true lockout. Wren All-Weather dampers are maintenance-free ensuring consistent performance over the life of the damper.
