Is the Floodgate/slow speed compression damping supposed to work in the fully open compression setting? Sram's website is a bit hazy on this, but suggests that it should, although I confess I don't know what "all DNA possibilities" really means.
...you can adapt to any terrain: Switch between "Open (with all DNA possibilities), "Threshold" (takes away the big bumps) and "Lockout" for fast rolling on smooth ground.
The thing is, my experience suggests that if the compression adjuster is in the fully open position, the low speed compression damping appears to do nothing and the brake dives easily under braking. Put it in "Threshold" setting and the low speed damping works a treat.
