Just got my bike and everything is fine so far, except for a squeak. Had to mount the front wheel myself, I'm thinking I should have added some lubrication there, but it seemed to already been done up with something.

Anyway it's a disc brake mountain-bike with front suspension. The M485 disc brakes [shimano] as far as I know are two-piston models.

Any ideas ? Something that may need some lube or anything, or should I put the wheel back on again ? Haven't had a bike since I was a kid, so I'm getting used to everything again Even thought the sound the bike makes when going a little faster is a problem, but now I'm just guessing it's the really fat mountain bike tires, combined with pavement and my 290 weight
