I was hoping someone with a 3x da Vinci would chime in to answer your question about the lockring securing the chainring cogs. Our old 2001 Joint Venture and our current 2016 both are 4x drivetrain like the photo. In that case, the chainrings are held in place by the threaded cog serving as the innermost chainring. Two chain whips are required in that case to remove the cogs. Certainly you will need to use a chain whip in conjunction with a tool for the lockring. As to what exactly that tool is, I donít know as Iíve never worked on a 3x da Vinci. I would suggest an e-mail or call to Todd to get the correct info!
