I had the good fortune to meet Sheldon on two or three occasions. He sold me my first Brooks saddle, and I ran into him at various shows. I also had email conversations with him on other occasions. It's sadly rare to find someone with such knowledge and insight, who is also so unbelievably kind and happy to help. It's thanks to him I ride fixed, brake on the right, no tread on my tires, have ridden 3-speed, had a fillet-brazed schwinn, and will soon get a trailer for my little son. We are richer for having known him, and poorer for having lost him.
RIP.
