Now, the dirty little secret of 650B: 650A is a very common tire size for wheelchairs. If the promoters of a modern implimentation of an intermediate bicycle wheel size had gotten behind 650A instead, wheelchair users could have benefited from a greater selection of good tires and lower prices. Post snippy little personal attacks if you want, but I'm sorry that benefitting the larger society wasn't important to the able bodied, highly mobile bike folks that made the 650B decision.

I had no idea wheelchairs were 650A. Economically, it would make more sense to use the 650A because of the bigger base of potential customers. I guess it's a lot more romantic to use tires from a bygone French stantdard than a wheelchair.
