Sheldon Brown is the authority on cycling. He works out of a cycling shop in Newton, Massachusetts (Harris Cyclery) and is cited by every bike geek as the authority on everything from Sturmey-Archer hubs to fixed-gear cycling set ups. In fact, there is an acronym devoted to Sheldon: AASHTA (As Always, Sheldon Has The Answer).
The man seems to live and breathe cycling and his site, Sheldon Brown’s Bicycle Technical Info is literally an encyclopedia of cycling. He also seems like a really great man gauging from his personal observations and approach to life.
Now it appears he has multiple sclerosis and has to give up cycling. This is tragic. Having made the decision to voluntarily give up cycling as a pastime after my accident in May, I know what it feels like to miss it, but can’t imagine the pain of having it taken away the way it has for Sheldon.
