Cobra Rad Speed vs Speed Zone Irons Review & Specs

For all the golfers in search of a complete set of irons that feel better, play faster and feature a streamlined compact design, you would do well to look in Cobra’s direction. Cobra is making some of the most high-tech, advanced irons on the market today.

Cobra’s commitment to modern club manufacturing is no more evident than in the 2 lines that we will be taking a look at in today’s review. The Cobra Rad Speed Irons and the Cobra Speedzone Irons are 2 of the finest offerings that the company has given us to date.

You can tell with high profile pros such as Bryson Dechambeau using the clubs at the highest levels of the game.

But which one is better overall? While one will help you advance your own game? Find out by reading our in depth review of both of these iron sets.

 

Key Features of the Cobra Rad Speed Irons

The Cobra Rad Speed Irons represent Cobra’s first foray into the realm of 3D printing as it pertains to golf manufacturing.

They feature a 3D printed nylon medallion which, after all is said and done, results in remarkably lightweight clubs with high MOI and an enlarged sweet spot.

It also means that you get very consistent feel, distance and speed with these irons. We’re not sure exactly what goes into the technology but the 3D printing also makes these clubs sound amazing while dampening harsh vibration even on off-center shots.

 

Key Features Of The Cobra Speedzone Irons

Perhaps the most interesting thing about the Speedzone irons is the “PWRSHELL” face inserts that Cobra uses in them. The inserts create a 35% larger sweet spot than previous model and add 8% to the depth of the undercut.

The result is irons that swing like a dream. The weight of the head is evenly distributed from the heel to the toe and the sweet spot is very generous. This is interesting because the insert sort of makes these a kind of hybrid between speed and forgiveness irons.

 

Quick Loft Comparison Chart

It’s important to note that the Cobra Rad Speed Irons come in either one length or variable length versions. The one length irons all have the shaft length of a 7 iron.

This is important as we look at the loft chart for both sets and because we will be taking a look at the length and lie of each set shortly as well.

For this review we tested the Cobra Rad Speed variable length irons because they are much more common at this point.

They also come in either right or left hand orientations and just like the Speedzone’s, you can choose from graphite or steel shafts.

The stock steel shafts on the Rad Speed Irons are KBS Tour 90’s while the graphite shafts are the same as the Speedzone’s: UST Recoil 460 ESX. You also get black Lamkin Crossline grips.

Who is Each Set for?

If you are looking for an exceptionally lightweight set of irons that still produce a ton of ball speed, the Rad Speed Irons will be better suited to your needs.

But if you are still working on accuracy, the more forgiving Speedzone irons will benefit you more.

 

Composition Comparison

The main difference between the composition of these two sets is injection molding and 3D printing. The medallion of the Rad Speed Iron set is 3D printed while the Speedzone’s are injection molded.

The Speedzone also have a slimmer carbon fiber topline which lowers the center of gravity in the club heads. Other than that, the composition of both clubs is essentially the same. Although we did like the stock Lamkin grips of the Rad Speed Irons a bit better than the Speedzone’s.

 

Performance Comparison

So which set performed better overall? The main advantages that the Rad Speed Irons had over the Speedzone’s were that they sounded better and they were lighter overall.

But that doesn’t mean that the Speedzone’s didn’t feel amazing. They swung extremely smooth and produced ball speed comparable to the Rad Speed Irons. Comparable, but not the same. In the end, we were getting better and more consistent ball speed from the Rad Speed Irons.

Final Assessment

The Cobra Rad Speed Irons certainly utilize the more recent technology and you can really feel it when you play with these irons. They are some of the sweetest sounding and feeling irons we have every played.

Overall we would say that they outperformed the Cobra Speedzone irons because we were able to get better ball speed from the Rad Speed Irons. As far as feel goes, this is a dead heat. The precision weighting of the Speedzone’s is on par with the 3D printed medallion of the Rad Speed Irons.

If you can spare the extra $100-$200 that the Cobra Rad Speed Irons will cost, we say go for it. But if not, the Speedzone’s are still a very high-performing iron set. So check your bank account and then pick one of these sets up!
