Stevie Churchill's signature 3-piece cranks from Primo were designed and built to handle anything he could throw at them, so you know they're built damn tough.

Their heat-treated 4130 chromoly construction results in some seriously tough crank arms that are finished with a custom arm shape, paired with a 48 spline heat-treated chromoly spindle.

The hollow chromoly spindle bolts help reduce weight without sacrificing on strength.
