If you read my article on Improve Your Cycling Part II and were “fascinated” by the discussion about gear inches, then you should follow that up by reading this article on Slowtwitch.com by Greg Kopecky on the evolution of the modern-day cassettes on bicycles, http://www.slowtwitch.com/Tech/Cassette_Evolution_4171.html.

Slowtwitch founder Dan Empfield has long been a bike techie and his website is one of the go to places for practical advice on bikes, gear, and how the parts all play along (or not!) on your bike. Good timing on my part to have preceded this article by a few days; luck over skill I always say!
