New article, derailerless drivetrains
: How to choose frame and rear hub for a happy combination on a bicycle without derailers: a fixed gear, singlespeed, internal-gear hub, coaster brake bicycle — and how to adjust the chain tension. This article compiles information from the articles on fixed-gear and singlespeed bicycles. but adds to it and puts it in one place. Most issues with all derailerless drivetrains are the same, but there are important differences to note, there is new equipment to cover, and there are additional techniques to describe.
SRAM and Sachs Internal-gear hubs

Updates to our main page on Sachs and SRAM hubs , and our page on the G8 and G9 hubs. We have located additional technical information from SRAM, and wehave fixed a number of Web links that went bad.
Updates to cyclecomputer calibration page
Links to instruction sheets for many more bicycle computers have been added to the computer calibration instruction page

Cycling in winter

Well, it’s time for this, in much of the Northern-Hemisphere anyway. Before I get onto my bicycle this morning, let me announce an article about winter cycling! Here’s one of my favorite photos of Sheldon…
The article covers winter bicycles, clothing, riding technique and choice of routes.There are links to other sites with additional information.
Don’t let the cold weather stop you. Getting out and getting exercise is a great way to defeat the winter blues. And you won’t have to dig out the car, or stand shivering at the bus stop.
Sturmey-Archer 8-speed Cable Pull
Information the current series of Sturmey-Archer 8-speed hubs has been added to the cribsheet of internal-gear hub cable pull measurements. Not quite the same as for the earlier series! Thanks to David Choma for the measurements!
Sturmey-Archer Pages Updated
Major update to the Sturmey-Archer pages:
* fixed links which S-A broke by redoing its Web site (that’s everything about current hubs).
* updated the list of hubs.
* Added new technical information.
Our cribsheet of hub model names and descriptions is a good place to start.
A quick quick-release lesson
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
Much-expanded page on stopping and restarting, with 7 (count ’em) embedded videos showing good and bad techniques: http://sheldonbrown.com/
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.
