Key Features & Design Performance
-
High-Torque Flex Claws: The defining feature of the Flex Chunk is its oversized, curved claws. These claws are designed to create maximum water resistance, resulting in a wide, rhythmic thumping vibration that sends strong pulses through the watereven during a slow drag along the bottom.
-
Dual-Injection Salted Balance: Keitech uses their signature two-tone process: a buoyant, unsalted upper section paired with a dense, salt-impregnated lower belly. This keeps the trailer perfectly balanced behind your jig, preventing the rotation or spinning often caused by inferior, unbalanced trailers.
-
Flat-Back Geometry: The top of the lure is flattened, which allows it to sit flush against the skirt of a jig. This ensures that the trailer moves in perfect unison with the jig, creating a single, cohesive, and incredibly realistic silhouette.
-
Acoustic Ribbed Body: The body is ribbed to trap air and release a trail of micro-bubbles during the retrieve. This visual and sonic cue acts as an additional strike trigger, helping predators track the bait in murky or low-light conditions.
Examples of Where to Use It
-
Small-Jig Trailing: Pair the 2 Flex Chunk with a Keitech Guard Spin Jig or any micro-jig head. The combination of the jigs skirt and the Chunks thumping claws creates a crawfish-in-defence posture that big perch find impossible to ignore.
-
Technical Dropshotting: When rigged on a dropshot, the large, buoyant claws hover slightly off the bottom. A subtle shake of the rod tip makes the claws snap open and closed, perfectly mimicking a defensive crustacean.
-
Urban Canal Micro-Punching: Its compact size makes it perfect for slipping into small holes in reed beds or tight crevices between lock stones, where standard-sized trailers would be too bulky.
Pro Tip
The Bottom-Hugging Pause: The most effective way to fish the Flex Chunk is with a bounce-and-pause retrieve. When the jig hits the bottom, let it sit motionless for 35 seconds. Because the Flex Chunk is buoyant, the claws will rise up in a defensive display while the jig head rests on the bottom. This hovering claw presentation is the ultimate trigger for a following predator that was previously undecided about striking.
Frequently Asked Questions
Which jig head matches best with the 2 Flex Chunk?
For the best movement, we recommend a #6 to #4 finesse jig head or a #6 to #4 finesse-style skirted jig. The key is to keep the jig weight light (1g to 3.5g) to ensure the claws retain their high-frequency thumping action.
How does this differ from the Keitech Little Spider?
The Little Spider features ribbon-like tentacles that flicker at high frequencies, which is ideal for a more subtle, shimmery presentation. The Flex Chunk is designed for a more aggressive, thumping action that displaces more water, making it the better choice when you need to trigger reaction strikes from active, feeding fish.
Does the squid scent wash off?
No. Keitech compounds the natural squid flavoring directly into the raw plastic paste during the manufacturing process. This ensures the scent remains potent throughout your entire session, leaching out slowly to maintain that essential predatory draw.
