Talk:Roller chain

I edited the paragraph saying motorcycle chains had been mostly supplanted by cog belts and other systems, because it is simply not true. Although this is true for american motorcycles, most motorcycles in the world still use chains, because of their better performance (in transmitting the power) and in spite of their higher wear. All racing motorcycles use chains, and so do most of the german and japanese ones and almost all chinese and italian ones. 85.28.65.75 07:32, 27 February 2006 (UTC)

I take exception to the claim that chain wear can't be chain elongation. I have a bicycle that each few years lose grip and need a new chain and the new chain is clearly much shorter each time. maybe 1 link per 30. 85.83.19.103 (talk) 11:24, 2 March 2009 (UTC)Dan Frederiksen
