Cycling has a very long history of innovation. What is old is new again. The Ravn uses 650B or 26 inch rims, just like my old Paramount tandem bike. The wider tires allow good float over gravel and dirt, and still don't weigh so much they hurt your spin on the road. Looks like a great setup for cycle touring where you'll ride some dirt as well as pavement.
