Primo Stevie 24mm CranksStevie 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. ###section### Product
