The Spro Mike McClelland RkCrawler 55 Crankbaits were designed to have a wide wobbling hunting action and have the ability to bounce off cover like no other crankbaits triggering aggressive strikes. Just hit the rocks and the RkCrawler 55 does the rest while rocking the school of fish. Most crankbait anglers know that deflection is the deal, and the new Spro Mike McClelland RkCrawler 55 takes advantage of a predator's built-in instinct and turns those natural instincts into secure hook-ups that show up at the weigh-in.
