The most popular cranks of all time are still awesome now!!!! These baddies have remained virtually unchanged for 30 years! Profile cranks are the standard by which all other cranks are measured. 4130 tubular chromoly with a 48-spline gun-drilled hollow (GDH) chromoly spindle to help save weight. Made in the U.S.A and used by more pro riders over the years than any other crank ever made! NICE.
