SUPERCROSS
"STRONGARM" cranks

Supercross started producing the "StrongArm"™ cranksets back in 1989. The first ones were made out of tubular 4130 cro-mo and used a 6 spline "redline" type spindle assembly. The current models use the same 6 spline spindle assembly but are made out of aircraft grade 7075 T-6 billet aluminum. Available in 175 and 180mm lengths only.

"PowerDrive" cranks

With the sucess of our 7075 aluminum "StrongArm"™ cranks, we started looking for a way to refine the BMX drivetrain. Using the same 6 spline B.B. assembly and the same 7075 T-6 aircraft grade billet aluminum we manufactured our crank arms in a more conventional style. These arms are available in 175, 177, 180, 183 and 185 mm lengths.
