What's new at sheldonbrown.com
Expanded coverage of Shimano Nexus 4-speed hub gears — we now have rebuilding information, translated from manuals in German which are the only ones we could find online — complete instructions for both the freewheeling/Rollerbrake version and the coaster brake version. Thanks go to Patricia Morris for assistance with translation.
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
Sheldonbrown.com’s angle on the Trek quick-release recall. This addresses technical issues which we haven’t seen covered in news reports.
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!
