Shave massive rotating weight off your drivetrain without sacrificing strength and durability! Superlite X2 Series sprocket kits feature an extremely light chromoly steel drilled front sprocket, a New Superlite X2 CNC machined black steel rear sprocket, premium D.I.D. 520VX2 or 520ERV3 gold plated X'ring sealed race chain cut to length and a rivet style master link. 

Superlite X2 rear sprockets are CNC machined in the USA to be the lightest and strongest 520 sprocket available today. The new X2 rear is 20-30% lighter than the Supersprox Stealth Tri-Metal sprocket and only a few ounces heavier than the AFAM Workslite alloy race sprockets.
