All of Radio’s new rims were designed in-house in Cologne, Germany. The argon pro rim is a fully flash welded, tubeless-ready rim, available in both front and rear specific models. Radio spent a long time working on these rims to guarantee that the rim profile maximises strength and reduces the weight. The end result is one of the lightest pro alloy rims ever produced. Tested on the track for the past x2 years, the argon pro is set to be an instant classic.
