explains it -----Original Message----- From: Michael Payne [mailto:[EMAIL PROTECTED] Sent: Wednesday, 05 March, 2003 11:54 To: U.S. Metric Association Subject: [USMA:25032] Gear Inches I recently received a copy of the Washington Consumer Checkbook (www.checkbook.ord), a Consumer Reports style magazine for the Greater Washington DC area. It's published by the Center for the Study of Services. On an article on bikes, it states the gear ratios of a bicycle are described in terms of gear-inches. I've never heard of this before, fortunately most everything on bicycles is in metric, including all the wrenches, the mass of different parts are expressed in grams in most catalogs. I'd like to find out what the correct term here is so i can write to them. I'm sure its supposed to be a ratio of how many teeth per cog.
