    Winner's Bag: Bryson DeChambeau, John Deere Classic

    Bryson DeChambeau comes up clutch on the 72nd hole at John Deere

Bryson DeChambeau came from four shots back to win the John Deere Classic for his first PGA TOUR title. DeChambeau used a SIK C-Series putter to birdie four of the final six holes at TPC Deere Run, but it was Cobra's King Forged One Length irons ended up being the most talked-about piece of equipment in the 23-year-old's bag. 

DeChambeau used the set of single-length irons to hit 17 greens in regulation during the final round,  — he knocked five approach shots inside 16 feet on the back nine — leading to a closing 6-under 30 that proved to be the difference. 

Unlike a traditional set that gets progressively shorter in length, DeChambeau's irons remain a consistent 37.5 inches (6-iron length) from the 4-iron through the 60-degree lob wedge. According to DeChambeau, the set allows him to create a repeatable single plane motion that's taken him to the highest stage in professional golf.

“I approach the game of golf a lot differently than most, primarily from a scientific standpoint,” DeChambeau said last year. “I have a more technical, unique swing than many other players, but there is a misconception that single-length irons are only for a single-plane swing like mine. That is simply not true. Regardless of how you swing and what your skill level is, you can benefit from the simplicity of a constant length set of irons."

The newly minted TOUR winner made history last year during the Web.com Tour Finals at the DAP Championship, becoming the first player in TOUR history to win a tournament using irons all the same length. 

The retail version of DeChambeau's irons is made from 1025 carbon steel and utilizes a five-step forging process. The faces and grooves of each iron are 100 percent CNC milled for spin and trajectory control, and a nickel-chrome plating is added that improves durability. 

Due to the length and weight requirements, additional tungsten was needed to increase the head weight in the longer irons. That meant drilling out a hole low in the head, and centered in the sole, for a tungsten plug that's only found in the irons at the top of the set. In addition to dialing in head weight, the tungsten improves launch and forgiveness.

Instead of filling in the hole that was drilled out in long irons, Cobra engineers kept the space unfilled in the short irons, which are lighter than traditional scoring clubs due to the longer-than-normal lengths. Going lighter raises the CG in the 8-iron through pitching wedge to promote trajectory control and spin.
