Welp, here I am again Monkies. I wanna tighten up/adjust my derailleur so that it doesn't smack and clang as much as it does. When I first bought the bike, the derailleur never clanged, so I know it can be done. It's an SRAM X.7 Derailleur with a 9-Speed Cassette and a SRAM PowerLink 9-Spd chain. A friend of mine recommended putting tri-flow in my derailleur cable housings. Another thought to get the Avid Rollamajig for my derailleur. Think these are good, or does anyone have any better ideas? Thanks!
