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.
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
