Article about tools to care for tires and inner tubes (pumps, tire removal and replacement tools, flat-fixing supplies) pulled out of the article on fixing flat tires, which was getting too long, and expanded.
New article, all about inner tubes: tire fit, the three kinds of valves, pump compatibility, tips and tricks.
Revisions to the Shimano Rollerbrake page: links to Shimano’s (finally) well-organized compilation of Rollerbrake documentation; information on installing front Rollerbrakes.
The article on special spoking patterns for use with extra-large hubs (for example, electric bicycle hub motors) has been improved with patterns which avoid twisting the hub shell for two of the hub and rim combinations. The article includes all the information needed to use Damon Rinard’s Spocalc (also on the site) to calculate spoke lengths for these patterns.
Check the level of spoke tension by ear — unless you are tone deaf, a musical pitch reference (pitch pipe, tuning fork, smartphone app etc.) is all you need to tell whether you have brought spokes up to the appropriate level of tension when building a wheel. It’s faster than using a tensiometer!
The page for Damon Rinard’s spoke calculator has been revised, with an updated list of online spoke calculators, several comments and links, and better formatting. Now also includes links to spoke-calculator apps for iOS and Android smartphones!
A new article on shimmy, or speed wobble — what it is, why it happens, how to prevent it and how to recover from it.
New article: Osman Isvan demonstrates how to remove and replace quick-release bicycle wheels, with two videos. Here’s one of the videos:
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
