I have been running a singlespeed mountain bike for quite awhile now, and have been experimenting with the pros and cons of different chain tensions. My friends have given me different opinions on the matter as well, compounding my confusion. If it's too tight, the drivetrain will wear prematurely. If it's too loose, it can damage the teeth on the sprocket and/or chainring. I hoped I would find closure by looking at examples of the myriad s/s 29ers from Dirt Rag's coverage of the North American Handmade Bicycle Show, but no dice: some had droopy chains yet others were high and tight. Advice before I kill my hub or break some teeth?
