History of 650B
650B.com found this article by Joe Breeze on the origins of the 650B wheel size. It is a really interesting read.
The 650B wheel size has been drawing a lot of attention over the past year. Many see it as the compromise between 29″ and 26″ wheels, and also a way to get bigger wheels to longer travel bikes. The long travel market is not a great fit for the 29er market, but with the 650B wheel size, frame and component manufacturers can stay closer to the 26 inch wheel specs to get increased travel. For those of you that have just heard about the 650B wheel size, you can see by this article that it has been around for a long time. With the introduction of 29 inch wheels to the mainstream market over the past couple of years, designers are looking for that next big thing to hit the mountain biking market. The 650B wheel size may be the answer…only time will tell. One thing is for sure, judging by Sea Otter’s offerings, manufacturers are jumping on the 650B bandwagon much faster than they did on the 29er one.
