yes, but containing carbon, and being carbon based, are two completely different things..... i definitely did not say that wood contains a carbon molecule so it is carbon. I simplified something that is carbon based, meaning its a string of carbons with other compounds branching off of it, and more than 50% carbon at that, can be identified as carbon in simple conversation. Sorry, should have said it was a compound of Cellulose, Hemicellulose, Glucomannan, Glucuronoxylan, several polysaccharides, and Lignin (all carbon based compounds btw).... because that is MUCH more appropriate for this here bicycle forum......
