The Cobra King Radspeed irons are the most technologically advance yet from the leading manufacturer. GolfReviewsGuide discover an iron jam-packed with new advances for 2021.

Like the new Radspeed drivers, fairway woods and hybrids, the design of the new irons is focus around the radial weighting concept.

Cobra have used the Radius of Gyration engineering formula, with the distance between the toe and heel weights increased to create the perfect balance.

With a PWRSHELL face incorporated for more flex and the first ever 3D printing on a golf club, the end result is faster ball speeds and higher ball launch from the Radspeed irons.

What Cobra says about the Radspeed irons:

“A breakthrough in Radial Weighting technology is met with the first 3D printed medallion, creating our fastest, most stable, and technologically advanced irons to date.

“The Radspeed irons feature our most advanced technologies including, Radial weighting, PWRSHELL, and a 3D printed medallion, to create our most innovative and highest performing irons yet.

“10g and 3g of mass is positioned on the toe and heel extremities to create the best combination of speed, low spin and stability for optimized performance.

“A 10g weight positioned low and in the toe area centers the CG and adds stability for more distance and forgiveness on off-center hits.

“3D printing offers unlimited complexity in design, allowing us to produce an intricate lattice medallion structure that saves weight and fine-tunes feel.

“A forged PWRSHELL face insert is made of a thin 17-4 stainless steel, and is designed to increase flex on the face and the sole for faster ball speed and higher launch.”

Cobra Radspeed Irons Design & Features

The most advanced irons Cobra have ever brought to market, Radspeed irons have a radical perimeter weighting design that is all about delivering more ball speed.

The Cobra Radspeed irons use a unique combination of high strength, low weight and 3D printed grille to drive the CG deeper than ever before.

Like the Speedzone irons of recent years, the Radspeeds feature a carbon fibre stripe along the top line to save weight, lower the CG and improve ball speeds.

The Radspeed irons have heel and toe weights (3g and 10g respectively) to create a lower center of gravity and the ability to utilise stronger lofts in this model.

The new RadSpeed irons feature a 3D-printed nylon medallion on the back of the club head that uses an intricate mesh structure to save weight and improve feeling by damping the vibrations felt on impact.

The PWRShell face features flex and is the first 3D-printed golf club, and the end result is faster ball speed and a higher ball start on these new irons than ever before.

Cobra Radspeed One Length Irons Design & Features

The Radspeed irons are also available in One Length options with the entire bag all measuring 37.50 inches in shaft length across the set.

Created partly due to Bryson DeChambeau’s requirement for the same length shaft in his irons, the Radspeed One Length all have a 7-iron length shaft incorporated.

All the same technology is present as the standard Radspeed, just with this model allowing you to set up and swing exactly the same no matter what iron or distance you are about to hit.

The PWRShell, perimeter Radial Weighting, 3D printing and carbon fibre strip are all present in the One Length range.

Verdict: Are the Cobra Radspeed Irons any good?

If you want more distance, greater forgiveness and increased ball speeds, the Cobra King Radspeed irons are the ones for you.

By reducing the weight, Cobra have managed to produced irons that you can swing faster and generate more speed and distance with.

The improvements on the SpeedZone irons that preceded the Radspeeds are impressive, and you can expect for significant gains in distance.
