What's new at sheldonbrown.com
We have expanded our article for individuals selling bicycles and components — which also holds advice for buyers. There is a new section about shipping.

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!

Sheldonbrown.com has compiled links to more cyclecomputer and bicycle GPS manuals, old and new, than you will find anywhere else on the Internet.
