A Vortex sprocket is a lightweight high-performance alternative to the steel stock sprocket.  Use Vortex sprockets to considerably reduce mass and to change your gearing (see below for details).

Changing Gearing
Adjusting the tooth count in front and rear sprocket changes the way the bike performs.
-A size increase in the rear sprocket and/or a decrease in the front sprocket will favor torque for increased acceleration.
-A size decrease in the rear sprocket and/or an increase in the front sprocket will favor top end speed.

Made with highest quality aluminum
-7075 T6 aluminum is the best grade material for light weight and durability
-The weight you save on drive components is multiplied as rotating mass
-Less rotating weight improves acceleration

CNC Machined to tightest tolerances
-Our unique manufacturing process creates a perfectly concentric sprocket every time
-This frees horsepower and extends the life of both chain and sprocket
-Perfected tooth design has less drag and reduces friction for better acceleration and deceleration

Attractive, Smart Design
-Vortex patented design offers a unique look
-Standard sprockets have a bright, polished look; clear anodizing helps prevent corrosion
-Mud grooves and coatings help keep components clean
-All sprockets available in single tooth increments
