    A Couple of Issues With My Rush

    1) If I bunny hop, the rear end makes a loud clank. When on a technical trail and seated, it makes a quite noise like a Lay's potato chip bag being crumpled.

    2) Rear QR comes loose. It this the QR's fault or what? It's the stock C' dale quick release.

    3) Some times when pedaling, I'll have the sensation that my chain came off the front chainring but it's still there. Is there an issue with my hub?

    4) My palms and arms felt more tired than my legs after an XC race. Is my frame simply too big, new grips or saddle position?

    Hopefully simple fixes will solve all this.
    -Thanks.

    Some ideas ......

    1) There is a Fox recall concerning noisy RP3 shocks (if this is what you have) .
    If so , contact Fox .

    4) Seatpost could be up to far , transfering you weight into your hands/bars .
    Get a proper bike fitting from a shop that knows what they are doing .

    2) Make sure the QR mechanism is lubed and when should be all the way in the dropouts with enough torque

    3) Mmmm, Could be your hub not engaging the pawls every so often? Does it feel like all of a sudden there's no resistance when pedalling?

    # 3 could also be a case of "ghost shifting" .

    By lubed, do you mean greased? And yes to # 3. I do feel like there is no resistance when pedaling.

    And, to the other fellow, thanks for the tip on the RP3 shock. I'll look into that. I highly doubt it it ghost shifting as this is Sram X9...no Shimano Deore. Although, it does need a new rear der. cable. And, my rear hub is a Mavic Crossland. I've heard that they don't engage well. I'll lower my saddle a bit, although it seems to be at an okay height.

    -Thanks!

    The rear hub sounds like it could have some sticking pawls, not uncommon with Mavic, which would cause it to "freewheel" while pedalling. It sounds like stuff that should be dealt with under warranty.
    Try some blue loctite on the QR threads and make sure the QR is really tight.
    If you have fatigue in your arms and hands most likely you have a lot of weight on your hands. This could be either a stem/top tube that is too long with the bars too far forwards, or the bars are too low relative to the seat. If you post a pic of you on the bike taken directly from the side it might help.

    Ghost shifting is a term used for the innner shifter cable hanging up and letting go , one or two gears at a time , usually under power .
    This is caused by dirt and grime inside the shifter cable .
    It is not a symtom of certain brands/models .

    The rear clunk seems to have been fixed by greasing the hardware. Only to a certain extent though. Trail riding, no noise, but if I get airbore and land, clunk.

    Rear der. cable had to be replaced, der. hanger was bent and hub was loose which all affected shifting.

    Arm / hand pain has been greatly reduced from moving my bars back.

    Forgot to get the QR threads loctited while at the shop. That should be simpple enough for me to do though, all I need is a bottle.

    -Thanks folks!

    Sounds like you got things sorted out

    I will let you in on one mystery "clunk/clack" that I
    had with my Rush .
    It took me the longest time to figure out but I found it .

    The rear derailer cable passes through the swingarm .
    At each end , the cable is supported by a rubber gromett .

    Both of mine fell INTO the swingarm and this let the cable
    clank around when ever you hit rough terrain .

    You will never get the grometts out of the S/A so I just wrapped
    a couple layers of electrical tape in the area of where the cable
    was held by the gromett and this held them in place and the noise
    is gone .

    It does not sound like that would make much noise, but I'll look into that.

    Thanks again to everyone who helped me out. It's absoulotley amazing what a HUGE differance a few minor adjustments can do. I lowered me seat a few inches, put my h-bars in a differant position and I feel much more comforitable. I actually got the Juicy Sevens to have some power (by putting Hayes rotors on), although Hayes hydros will be on there shortly. Clacking is is occuoring, although the other noise was stopped by greasing the hardware. Other issures mentioned were resolved.

    Now the bike is a ****in rocket on my local trails and although they (trails) are of high quality, they all of a sudden feel buffed out as though I'm riding a slalom course. I'm probabling riding 2x-3x faster thanks to you guys.

    -Thanks again!
