Message: >just out of curiosity, are shot peened parts, such as handlebars better than heat treated ones in terms of longevity? Thanks. Shot peening is used to relieve stress after heat treating for increase in fatigue life. That is to say, all shot peened parts are heat treated. Shot peening can also be used to make a lightweight part last as long as a heavier part (in regards to fatigue life).
