New article: Osman Isvan demonstrates how to remove and replace quick-release bicycle wheels, with two videos. Here’s one of the videos:
Stopping and restarting

Crib sheet of internal-gear hub cable-pull measurements

NEW – Crib sheet of internal-gear hub shifter cable pull measurements
The main thing this shows is that there is very little compatibility, though there is *some* — mostly among three-speeds, though not always among them either. I thank Alex Wetmore and Jeff Bertolet for help with this page.
Raleigh Twenty page additions
Additions to the page on Raleigh Twenty bicycles — more detail on bottom-bracket replacements, headsets, brakes, handlebars. This page gives specific ideas about customizing the Twenty, and highlights Sheldon’s do-it-yourself approach in general, taking advantage of the strong points (in this case, the frame) of a run-of-the mill bicycle to upgrade it into a one that performs, and looks great too.
Addition to page on SRAM G8 and G9 hubs
John has added some owner comments to the page on SRAM G8 and G9 internal-gear hubs. Opinions are generally very positive.
Quick releases
I’ve responded to a request from a reader for more information about quick-release skewer lengths by going further, with a major expansion of the article about quick releases. The article now covers wheel installation, secondary retention devices including the much-derided “lawyer lips”, and much more. — http://sheldonbrown.com/skewers.html — John Allen, for sheldonbrown.com

More indicator spindles
David Prosser of Sturmey Archer has sent information about a couple of Sturmey-Archer indicator spindles (the chain-pull assembly which shifts the hub). It is now on our indicator spindle page. Thanks David!
