(When I say chain guide, I'm referring to the ones with the lower pulley that add tension to the chain...mainly for DH bikes)
With clutch derailleurs, what's the point nowadays with chain guides having that lower pulley? When chain guides were designed, we didn't have derailleurs with a clutch mechanism. But now with clutches there's a lot less derailleur cage movement, so I'm wondering what's the point of adding extra tension to an already tensioned chain? Unless you're running a chain guide with lower pulley to take up any little slack there may be left in the drivetrain?
