For ClubTest 2021, we tested and reviewed 53 new irons to help you find the right one for your game. (For more on our testing process, click here.) Below are the results for the Cobra RadSpeed irons. You can find the full list of irons and test results here.
Our take: It’s impossible to miss Cobra’s RadSpeed iron. The electric yellow markings situated in the cavity are meant to make it stand out, and more than a handful of testers confirmed they “absolutely loved the look.” Said one tester, “You can’t miss these irons. They certainly have a look my son and his buddies would embrace.” But looks will take you only so far. What many testers noticed was that the 3D-printed nylon medallion and detailed lattice structure served a dual purpose, enhancing feel and shedding unwanted weight at the same time while upping the iron’s street cred.

Cobra Radspeed Irons
The details: Cobra took an unconventional path to bring RadSpeed to life, partnering with HP and Parmatech to 3D-print specific parts of the iron. Weight saved from the cavity was repositioned in the low toe and heel to dial in head weight and improve overall forgiveness. To increase speed and optimize launch, the irons also have what Cobra calls a PWR Shell face insert made from 17-4 stainless steel that’s built thin and flexible. A carbon-fiber topline gives the head a unique look in the address position. (You’ll notice it when you look down.) In addition to the standard-length version, a variable length provides progressive head shapes, grooves and hosel lengths to optimize launch for every iron in the set. Very impressive stuff.
