Proper Adjustment fo Redline Chain Watcher?(4 posts)

Either these things don't really work well, or I don't know how to install it. How should this doo-hicky be positioned relative to the chain? Should the nose be slightly above the chain, or even with the pins? Thanks for any help.

Never used one of these, but it looks like the Deda Dog Fang fing, which I believe you should set up just below the line of the chain, leaving only a small gap between the fang and the chainring that the chain cannot fall through. I would guess that you can't set it up level with the chain because the inner part of the FD cage is in the way, stopping the chain travel horizontally - the chain keeper stops the chain dropping down if you have over shifted, and should put the chain back on the ring.

Lennard Zinn has this to say

Try a Third Eye chain watcher or a Deda Dog Fang. These little plastic gizmos clamp around the seat tube, and you set the height and rotation so that it pushes the chain back onto the inner ring whenever it tries to climb off. Either one is a no-brainer to use and completely effective. --Lennard

Good luck
