I build scores of 650B wheels each year and keep a large stock of 650B rims, tires, and tubes on hand. The 650B wheelsize is commonly used used for fast, versatile, and rugged bicycles with tires larger than 35mm tires and fenders. The wheelsize has enjoyed something of a renaissance in the last few years but never went away for good reason. Builders like Herse, Singer, and Goeland turned the wheelsize repeatedly when designing speedy, robust bicycles suitable for varied riding surfaces.  Follow the links for 650B specific components.
