Product Description

Primo put a little thought in to the Primo Pro Chromoly cranks.  With a 22mm heat treated spindle and wrap welded pedal and spindle bosses these things are going to be hard to break.  Primo even wet as far as shaping the arm a little different than most to help prevent denting.  Good stuff!

  • Spindle Splines: 48
