    My Lefty's Rebound Knob is Driving Me Insane!!!

    The head on my '06 DLR2 stripped a while ago. I Had REI drill it out. I got a replacement from Cannondale....a few months later....

    It is now time to reset the bearings. The head had once again stripped. I search all over MA to find the only bike shop with a spare rebound knob as it will take cannondale 2 months to get more. I find one. They install it. I get home and can't get it off. REI can't get it off. The shops are now telling me to get another rebound knob and have it drilled out once agin.

    I have the Mt.Snow National race in about 2 weeks that I'm qualified for.

    Sounds like some irrational exhuberance, taken out on a poor little allen head set screw. Tighten it a bit less, if you can get one to DIY, you'll be happier. Note, use a nice fresh wrench, a worn one will make it feel stripped faster.....

    Okay. After you take the knob off, there are "split rings" and a nut around a prong.(?)
    Cannondale says not to loosen or tighten the nut (#10)...I think I may have done this during the first time I reset the bearings. I also may have turned the prong(?...not sure what to call it) a bit for whatever reason. Would this have anything to do with my problem?

    Well, I'll get another wrench and take it to a hardware store to see if they can get it out without damaging anything....which apparently they can do. When I talked to the emplyee at the bike shop, he said they can use a reverse (???) method to srew it out that should not damage the rebound knob or the screw. He also said the screw should be a 440...?

    I'm sorry Mendon to have you try to make sense of all this...I'm a mess right now and hopefully this can all be taken care of SOON and no more money will be wasted.
    -Thanks
