Yes. It's official I'm afraid.
According to the Harris Cyclery website...
Dear Harris Cyclery friends and customers,
It is with heavy hearts that we convey to you the news that Sheldon Brown has passed away. Our thoughts go out to his family at this time. The cycling community has lost one of it's most passionate members. He was a valuable BikeFo member.
