Re: Ditch the idler!!!
If you run without a tensioner make sure your chain alignment is near perfect. The tensioner serves as a chain guide that helps the chain onto the rear sprocket. Any misalignment and you're asking for trouble at speed if the chain starts to waver from side to side. Just a word of caution for those wanting to get rid of the tensioner,(idler).
