Reorganization of headset tables
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.
Shimano 4-speed hub gears
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.
Shimmy, or speed wobble
A new article on shimmy, or speed wobble — what it is, why it happens, how to prevent it and how to recover from it.
