This document is provided as a historical reference.  Some of the information is no  longer current. For instance, Charlie's opinion about chain/drivetrain maintenance has evolved radically.  On this drivetrain maintenance issue, we will work to supplement this information with the latest information.  Charlie is especially obsessed about drivetrain maintenance because it can prevent so much waste and expense while making the bike work better...and it is easy...it just takes the knowledge and willingness to do it.
