In this special episode we were lucky enough to talk with Josh Poertner, President of Silca, and general bike tech legend. Josh tells some great stories, including why your road bike has disc brakes. He also confirms a lot of what we have been saying about the need to build a strong bike community. Bikes are becoming more complicated and difficult to set up and maintain, and new riders, or experienced riders getting new tech, will need help from the cycling community to keep their bikes safe and working. Listen to the end for the Chumps' take on what Josh had to say. Hopefully you will be inspired to make a difference in your own local bike community!
