The 777 is a double walled, 36 hole, welded rim with a concave design for increased strength and stiffness. Strong enough to hold up in the streets, but still keeps the weight down!
AR/777 rims are 777 rims anodized in the USA with an aluminum oxide treatment used on AR 15 Assault Rifles. The aluminum oxide treatment bonds to the rim and is incredibly hard, increasing wear resistance for those of you who choose to run brakes. The AR Black finish looks different to the regular black.
