    Resonation in front wheel at 15mph +

    Hello

    I am getting a whrr whrr whaaaa ect..... that resonates when I am at speeds > 15mph otherwise it's pretty quiet. I have checked the brakes and they look adjusted fine, the rim is true and the spindle has no bends or anything. The sound becomes more pronounced when I turn the tires appear fine and there is nothing on them. Do I just have a hosed hub or? Thanks for any help.

    Front or rear wheel?

    I got my new bike a couple of weeks ago and was getting the same thing.. (Trek 6500) For me it was the reflectors on the tires that was causing it and I'm glad I saw it mentioned in a previous post here.. I 1st called the shop right away and they said "Oh that's just because of the knobby tires on your mountain bike" Still didn't seem right so I took off the reflectors and that did it. I don't hear anything now.. That might not be the problem but it sure worked for me.... Or maybe it is the knobby tires like my shop mentioned...

    yeha the reflector on my 4500 did the same thing. take it off or slide it twards the hub more to wedge it betwene 3 spokes better.

    And my bike does that on pavement , seems to be the tires.
    Though I haven't played with the reflector at all, maybe I'll try that too.
    Does this happen in general, or just on pavement?

    And what's wrong with keeping people on their toes? You folks shouldn't be running reflectors anyway.

    Plastic reflectors as a whole are a waste of weight, time, energy, and space, on a dual purpose bike plus they end up as trail litter.
    What you should do is get some Reflective Tape
    and apply like so to the frame:

    and like so to the rims:

    This way there's nothing to break off and you have reflectors. Everyone is happy.

    Sorry to take so long to get back, I am going to try the reflectors. I did think that this may be the issue but didn't try it yet. Thanks for the suggestions and the humor, I will also be getting some tranny fluid and soking my front hub in it, haa ha hah ha h -joke

    mine does it in the rear...I have an 8 inch rotor and that resonates between the pads at certain speeds. To give you an idea of the sound...its like a kx500 with a loose muffler spring.
