In development: A tuff-boy 650B rim by Velocity and musa, tentatively called the Atlas. An inch wide, with thick spoke bed and sidewalls.
Also, from Alex in taiwan, an even tuffer-boy rim based on a 32mm wide bmx rim. Early mtn bike rims were 32-or-so mm wide, makes sense for wide tires. You get more tire volume (height and width) and less tire roll at lower pressures. The marketing challenge, if that's what it is, is going to be presenting a super smart rock solid rim for heavy riders or heavy use while at the same time respectfully answering questions such as "how much does it weigh?" If a rim is widened to the point where it's really optimized for 40-55mm tires AND is thicked up in the sidewall for longer life AND has a thicker spoke bed to longer resist cracking at the hole AND has a slightly taller braking surface for more tolerance in brake adjustment, then the overall volume of metal is going to be about 75 percent greater, which means 75 percent heavier. Of course, it'll take 2x the wear and abuse, so is a bargain (for certain kinds of riding). Anyway, I expect more 650B rim options as the size gets popularized---which is happening big time these months.
