Bike making a strange noise
 

My bike seems to be making a strange noise. It almost sounds like 'wee wee wee wee", and a high pitch. It seems like the frequency changes when my speed changes, so if I speed up, the frequency speeds up, and the reverse is true. It will make the noise, then sometimes not make the noise for 10 miles. It also seems like it only makes noise at a higher speeds (15mph or above. If I had to guess, I would say its the front wheel, but I'm not positive. I know the breaks are not rubbing. The bike is a Felt Z85 with only about 400 miles on it.

Nothing I seem to do affects the sound, shifting weight forward or backwards, stopping pedaling, etc. I'm going to take it to the bike store to have them look at it, but I'm a bit worried they won't be able to get it to make the noise. I noticed it a bit on Tuesday, then none on Thursday (20 miles), and it was back on a lot of yesterdays ride (75 miles).

I suspect it's a rubbing at the hub. Many hubs have rubber bearing seals, and sometimes they get dry and scream this way. If you have a rubber seal. see if you can lift o flex it and put a drop of grease or oil under it.

Does it go wee wee wee all the way home?

^^ roflpmsl in stiches lol lol lolololol trian! Rofl copter! I cant even breathe!

Make sure that the end of your front derailleur shift wire is not rubbing on the rear tire. If so, the noise will change/disappear as you shift chainrings. Check your brake wires, also any seat or handlebar bags. Finally, check that the rear tire is not askew and rubbing on a stay or your kickstand.
