    Been having this issue with multiple sets of Q3s, even with different suspension setups. Previously was on stock shock now have a TTX and same issue, same person that setup the suspension. Running 30/30. Do you guys think that the rebound is too fast? Should I had maybe 2-3 clicks of rebound?

    Most importantly, the bike feels pretty solid. I just ask as I'm sure it's something suspension related as I looked at many others running the same tires and their tire doesn't have the leading edge, which tells me it's not the tire itself.

    I'm working on the same thing also. I was playing with the rear rebound a little this weekend trying to cure that problem along with the Bucking Bronco onto the front straight problem.

    Could be a rider/throttle adjustment. I had wear like that when I used to wait too late to start applying throttle.

    If the leading edge is rised, rebound is too slow, if the back edge is rised, rebound is too fast.

    Here's my tires after installing new TTX

    I wonder if I will ever be at a level to where I can understand Dave's black magic. I'm on my 2nd time through of the "Suspension for Mortals" where Max McAllister gives a 3 hour seminar and I still can't understand what half of what Dave Moss says.

    So with that being said...

    Problem: "Rebound To Slow"
    Solution: OPEN UP?


    Problem: "Rebound To Fast"
    Solution: CLOSE UP?

    If the leading edge is lower than trailing edge, according to tire rotation, increase the rebound setting.......I.e. slow it down.

    If the leading edge is higher than the trailing edge, decrease the rebound setting.......ie.....speed it up...turn screw counter-clockwise

    Other than tires what are the other effects of rebound being to fast? Or slightly too fast?

    Well I was getting a pogo effect on a high speed corner entrance so I "Slowed Down" the rebound and it started to smooth things out.

    I would say stability in direction change, throttle on/off transitions, braking stability... thoughts?

    Grattan's character is the varying degree of elevation throughout. Rebound helps that. As long as it's not packing.

    I didn't have stability issues with mine and I only got that bouncing effect at Barbers coming out of turn 5 (Charlottes Web) where the dip is right as u hit the middle straight. I would get a slight wheelie. My bike settles in nicely into the curves and transitions well (my tires still look like above leading edge shaved trailing edge raised), maybe I am not going fast enough to be affected. May also be my body position as well.

    Changing the rebound setting and looking for results doesn't happen in one session most of the time. Once the tire has started to wear with the leading or trailing edge high, it may take several sessions to start seeing a change. It takes even longer on a street bike that isn't ridden nearly as aggressively.

    Depending on how pronounced the rebound is off, a good rule of thumb is to make small changes.....two or three clicks and then go ride. If it's way off, I might go six or so clicks....it just depends on how far off it is.

    Not sure if mine fits into the severe level, so I think I will start with 2-3 and check the tires after lunch. I will be at BHF this weekend!

    According to this thread I need to increase my rear rebound? As in turn it clockwise and slow it down?

    This is a image of my rear tire, you see the fraying of the trailing edge...
