I'm building a new bike with an XT 786 rear mech. It's got that new clutch lever that is supposed to inhibit derailleur movement and reduce chain slap. I hear it's all the rage so I bought it without knowing much about it.
Is this something you turn on and off during a ride, like a shock CTD setting or something? Or is it more like you flip it on and don't turn it off unless/until you need to remove the rear wheel?
Are there other times when you would want to turn it off?
