The BB Trigger-21 is BKK's stinger rig for big soft baits developed in collaboration with Black Bay Lodge. Undergone through extensive testing with numerous big Irish pike, this stinger rig boasts a set of features that re-defines the concept of a stinger rig: Front spring to secure the rig onto the bait Tempered stainless steel components for robustness and extended durability Stiff structure that perfectly adheres to the bait profile Pins covered in plastic material to secure the rig to the bait body BKK Spear-21 treble hooks for unparalleled penetration Stainless steel swivels to buffer torsional forces Pairable with the BB lead system to adjust the sinking speed and pattern of the bait (2.5g lead included in the package) It comes in multiple sizes to suit a wide variety of soft baits. Adding the BB lead along the rig also stabilizes the swimming action of the lure and enhances its attractiveness during the fall. Ideal for stop-and-go retrieve. Size range 1/0 to 4/0, available also fit with Spear-21 UVO.
