What's new at sheldonbrown.com
Major revision to our article about Sturmey-Archer indicator spindles — which ones fit which hubs. Also a new article on how to measure for an indicator spindle in case you can’t identify the hub. Many thanks to Bruce Dance for suggestions, corrections and new material!
Pages about tandems and tandeming Sheldon Brown and family on home-built tandems[/caption] have been updated. We have more about disc brakes, brake levers, Gates synchronizing belts, and details about upgrading a cheap beach-resort tandem to ride with a child.
Our article about cassettes has been updated to include information on 11-speed systems. Interesting — all major brands of 11-speed casettes now have the same sprocket spacing. Most rear derailers and shifters are not compatible, though. We can tell you which ones are.
New post on bicycle chain and sprocket wear
Information has been added to the Creaks, Clicks and Clunks page to help you diagnose several more problems. The page now covers more types of cranks, the noiseless lurches and bumps which occur due to tire damage, chain too wide for the sprockets, worn-out bottom bracket bearings, chain rub on front derailer…
New page on SunTour Perfect, Pro-Compe and New Winner freewheels. These are no longer made, but there are a lot of them around and they offer many options including the ability to work with older frames that have smaller overlocknut distance than current frames. We have information on choosing, maintaining and customizing these freewheels.
We have a new article on how to perform the precise measurements needed to determine whether bicycle parts fit each other, without expensive and fragile tools. There are a number of clever tricks — for example, you can test the width of the square taper of a cotterless crank with an ordinary open-end wrench!

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.
