I just read on David Churbuck’s blog that Sheldon Brown passed away. I never met him in person, but his wealth of knowledge about bicycles helped me restore an old Raleigh Sport and created an obsession with fixed gear bikes. I finally managed to build one up after poring over his articles on the subject.
Some time back I learned that he was having difficulties riding due to multiple sclerosis. He’ll be missed by the cycling community.
