    Just purchased 9x Stumpjumper Pro M2, Question inside.

    I just purchased it for 425.00 from a user on craiglist, everything was in MINT condition, all the parts were clean and well maintained.

    The parts that came with were as follows, XT front derail, XTR rear, XT brakes, XT rear hub and so forth.

    The bike ended up weighing around 24.xx lbs, as i just used a scale from a bathroom.

    My problem: While riding the bike, and rocking back and forth to pedal quicker, there is a creaking noise that comes from the handle bar location. The handle bar has a carbon fiber look to it so I'm not sure where the noise is coming from, the stem? or the handle bar itself.

    Any easy ways of testing the noise? or figuring out the location?

    My parents are away with the cam, so i cant take pics currently, but comes Tuesday i'll get some for ya, so you guys can see what you are dealing with.

    possibly the seatpost

    I have a similar stumpy (mine is an M2 I got new in 93) Mine has a creak in the seatpost-seat tube. Depending on how often I remove the post and re-lube it the level of the creak changes.

    It sounds like you might be out of the saddle by your description so that might not be it.

    another possibility might be the cable stops (the first stop coming from the bars, mabey a dab of lube there...), or the headset.

    This is a rough and very inaccurate picture of it

    but it is adjustable, and has similar features.

    If it is adjustable, then could it not be the bearing on that which is giving you the creak??? Have you tried loosening that, giving it some lube and retightening?

    No, i haven't done any maintenance on the bike, as I purchased it 3days ago, and had only one day of riding, every other day was rain/rain/rain.

    I'll give that a shot.

    quill stem uses a threaded headset, which could be loose, it would look like this..



    or is it a threadless which would look like this;

    Problem fixed, i loosened 3-4 bolts, sprayed some Triflow, and the noise is gone.

    I also moved the adjustable stem lower, and that might have been the issue because it might have been touching the very top of them stem.

    Anyways, thanks for all the replies, and the problem is all done.

    It looked more "threadless" then quill.

    It's a threadless, but adjustable stem.

    From the pictures it looks like a standard 1 1/8 diameter steerer tube. Just check, it should be stamped somewhere, perhaps on the stem, or measure it yourself. Older steerer tubes used to be only 1 inch, in which case you wont be able to buy a new fork. But if it is 1 1/8 inches, as it looks, anything today will work.

    M2's are 1 1/8

    So, yes you can purchase a threadless fork in 1 1/8" steerer tube. You might want to find your prefered rise with the adjustable, take it off, then find a stem that will match that rise. That way you will never have to worry about it loosening on you, or the weight.

    Well granted i weigh, 125lbs of feathers, lol...

    Got any recommendations? I should keep it under 100mm? or should i go even less?

    Like i mentioned, i do weigh less then most riders, i'm looking for a suspension that i can feel as well as something that wont flex too much.
