Sheldon Brown.  A wealth of information, a dedicated rider, and gone but not forgotten.  You have probably been to the website before, if there is something that seems like it might be possible on a bike, Sheldon Brown has likely tried it.  Sheldon Brown was diagnosed with Primary Progressive Multiple Sclerosis in 2007, and passed in 2008 from a heart attack.

A technical authority on all things bicycle, I found the answer to many tech questions I had over the years.

Shirts are available now, with proceeds benefiting Massbike.org, an organization Sheldon believed in and supported in his life.
