Picked up the bike from the dealer after the HD premium dual cartridge install. Right away I noticed that the brake dive is much reduced and the front end does have a stiffer and more planted feeling, no lack of feedback from these at all. I need to take it easy until the new rear tire gets a few miles on it - just my habit, might not be needed but it's the way I've always done it - Later this weekend we have a nice long ride planned and after that I will have a better idea of just how much improvement has been made. At this point it seems to me like it's a definite improvement.
