SRM - The inventors of the power meter! Since 1986, Uli Schoberer and his team have continued to improve and perfect their spider based design. The products from the German company SRM have been the industry’s gold standard for many years. With riders like Greg LeMond, Lance Armstrong and Jan Ullrich having put their trust in them, it is easy to understand why SRM is so renowned in the industry and especially in the pro peloton.
