What's new at sheldonbrown.com
Our tables of headset sizes have been reorganized to make it easier to determine which headset can be made to fit which frame and fork. Fork crown race seats can be milled down and head tube race seats can be enlarged. The tables now are in order of head tube race seat size, as the frame is the more difficult and expensive to replace, followed by fork crown race seat size. The tables are used in the article on headsets and several other articles.
A new article on shimmy, or speed wobble — what it is, why it happens, how to prevent it and how to recover from it.
http://sheldonbrown.com/650b.html : added more info on “27 five” tires, and a photo (thanks to Aaron Goss!).
http://sheldonbrown.com/tire-sizing.html : added several tire sizes
Update to the page on “26-inch” tires — there are actually 5 common tire sizes called 26-inch and if that isn’t enough one is also called “27.5” The updates cover new developments in availability, naming and tire widths.
Several tire sizes have been added to the Gear Calculator:
Fatbike sizes: 26 inch tires, 26 x 3.8, 4.0, 4.25, 4.7
Wide 29ers: 29 x 2.7 and 3.0
32 inch and 36 inch (common on unicycles).
Here’s a high-tech product which deserves to be used in every new bicycle infrastructure project. The linked page gives a thorough description and videos!
