Official notice of his passing.
Sheldon Brown was THE Internet bike tech guru for many years. He worked at Harris Cyclery, a family-owned shop in Boston, and it was one of the first shops with a Net presence.
Among other things Sheldon put together a fabulous listing of bike tech articles, which became a standard reference. We did a bit of correspondence over the years, and I got a small thrill when I found that he had linked to my website, mainly due to my page on the Raleigh Twenty folding bike, of which he was a fan.
Sheldon's health had been suffering over the past two years, and he'd been diagnosed with MS. It was heartbreaking to read how he could no longer ride a upright bike, and even with his stable Greenspeed trike he could not ride as far as he used to. He talked about his travails in his journal, and he was posting right up until the final day.
Rest in peace Sheldon. You were an inspiration to far more people than you may have been aware, and certainly to me. I started my website because of people like you - people that so freely gave their knowledge to others. You will be missed...
