b'Jurgen Landrie has been wrenching on bikes for WorldTor teams for decades, so he has seen how much bikes have changed over the years. But just in the last five years, it seems like that evolution has accelerated. \\n\\nLandrie joins VeloNews tech editor Dan Cavallari on the VeloNews tech podcast to give us a sense of how and why bikes have evolved so rapidly in the last few years, and how mechanics at the top levels of the sport are adapting and taking on new roles to ensure riders get all the benefits from aerodynamics, body positioning, materials, and more.'
