Xtra Speed New 1.9 and 2.2 Beadlock Crawler Wheels are a New Arrival at rcMart! The 2.2 rims concentrate the mass all in the wheel, which ejects the need of a beadlock ring. This allows the wheel insert to sit further inside the wheel which in turn generates more sidewall grip! Comes in both red and blue, and many styles for you to choose from!
