Today I entertained myself by measuring a bunch of hubs, sprockets and singlespeed freewheels.
I discovered that there is considerably less standardization in terms of chainline than I had
supposed, and that if you want to get it right, a bit of extra care may be called for.
I've put my data into the Chainline entry of my Bicycle Glossary, though this may at a later date
grow into a stand-alone article on single speed chainline.
The main Chainline entry is at:
http://sheldonbrown.com/gloss_ca-m.html#chainline
The tables of sprockets, freewheels and hubs are at:
http://sheldonbrown.com/gloss_ca-m.html#chainline1
I welcome additional data points from readers.
