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!
If the chain falls off or jams
New article on how to prevent chain incidents and how to recover from them. Did you know that you can re-engage a dropped chain without getting your hands dirty?
Biopace chainrings
We like Shimano Biopace non-round chainrings, and they are reliably available on eBay. We have expanded our article on how to choose and use them.
Sturmey-Archer indicator spindles
John has compiled an article with dimensions of most kinds of Sturmey-Archer indicator spindle — the little rod and chain which the shifter cable pulls to shift the gears inside the hub. There are over a dozen different indicator spindles, with different lengths, intended for different hubs — but importantly, there is a lot of compatibilty among them.
Article about Rohloff hub
We have spiffed up an article about the Rohloff 14-speed internal-gear hub which had been lurking on the Harris Cyclery part of the site and placed it with the other informational articles.
Sheldon’s Articles for Adventure Cycling
From 1999 through 2007, Sheldon wrote the column “Mechanical Advantage” for Adventure Cycling, the magazine of the Adventure Cycling Association. He covered a wide range of mechanical topics, oriented toward the needs of the bicycle tourists with the Adventure Cycling Association serves. All of these articles are online, and we now have a convenient table of contents for them on our site.
More about belt drive
John has revised information on belt drive to cover the Gates Carbon Drive.
Chains
Major update to our article on chain maintenance — bicycle chain was developed in the U.K. and is dimensioned in inches. Most of the world including the U.K. has gone over to the metric system. How do you tell whether a worn chain needs replacement using a ruler marked off in centimeters? We’ll show you how! (Inches too, of course.)
Upgrading old road bikes
I’ve filled out and Harriet has formatted Sheldon’s page about upgrading old road bikes, which Sheldon left as a work in progress.
