    Mice

    My bottom bracked sounds like there are mice in it. It squeaks. This started several days ago I rode home in the rain then washed my bike the next day. I lube everywere I can think of after I washed it. Is there any way to lube the bottom bracked without taking it apart?

    Not that I know of. And is it making a grinding dirty noise? Sounds like water got in, but when that happens for me, it always has a grinding dirty noise.

    Any good American will watch THIS -and- WHERE WAS MY BIKE MADE?

    IME I've heard high pitched squeaking coming more often from plastic parts rubbing together. And groaning/creaking from bearings, dry B.B.s and etc.
    Do you have a seatbag brushing up against your seatpost or rails? Is your chain lubed?
    First off, how are you washing your bike? With a rag and simple green? Or with a power washer? I would only use a hose in the lightest sense and never apply pressure.
    What kind of bottom bracket do you have? If you have one of them fancy 2-piece cranks it's not hard and only requires 2-3 tools.

    Lastly, unless you have all the tools yourself, it never hurts to have a bike shop go through and make sure every bolt is tight and torqued properly. A few weeks ago I had what I thought was a dry/creaky pedal. Turns out that my driveside crank arm bolt had loosened and the creaking was coming from the spline interface. Loctite and an 8mm allen wrench took care of that.

    My $.02.
    p.s. I'd be interested to hear feedback on what it was. I think more people would post suggestions and tips if they'd received an answer in the end. Sort of like stump the chumps on Cartalk.

    Are you sure it's the bottom bracket?

    I've encountered that noise a few of times. In every case it's been a hub that had a dry neoprene seal where the axle exits the hub shell. A tiny shot of silicon lube quiets it.

    It only happened when I pedaled and both sides. i only pedaled on one side and unsnapped the other. I really did sound like mice or birds. I dont think it was the seat. I just went out and lubed everything I could find and tightened everything. Nothing seemed loose. I oiled the chain too well before I left the office and I did not hear it as much but there was a lot of traffic noise. Anyway I just went out for a short ride and no squeaks. It does not answer what it was though, since I squirted everything that moves. Also i might becoming a bicycle hypochondriac. I noticed when I stand on both pedals they make a firm popping sound. Again i checked that 8 mm allen bolt and it seems tight. Maybe I need medicine instead of my bike. I am going for a long ride in the AM I will see if it comes back. Could I cause any damage if I ride about another 1000 miles, i dont want to take it to the shop as nice as it is out and as close to winter as it is. Not much nice riding weather left.

    O I checked my back rack and it was tight, it has squeaked before and I do wash my bike with simple green and not even a nozzle on the end of the hose. Again thanks for the help.

    Standing on both pedals creates a popping noise?

    I've had heaps of these issues. I ended up buying a whole toolkit, cause you need like 3 tools to take off the bottom bracket and its nearly cheaper to buy a whole toolkit.

    On my old tiagra road bike, I got a click per rotation or maybe two per rotation I don't remember. Opening the bottom bracket, greasing and tightening everything back up got rid of the problem.

    Then the bike I currently ride, I was hearing clicking on the right. I took apart the bottom bracket and did the same but this time, it didn't help. It ended up being the crappy pedals, and I got some shimano.

    Today I was thinking I was having the same problems. It was frustrating me majorly. Turned out to be the little wire end from my front derailleur banging on my frame. So annoying!!

    ...Anyway I think the best thing is to buy a toolkit and learn to open up your bottom bracket. Its really worth it. You'll never regret spending some money on tools and discovering the simple mechanisms that hold your bike together.

    Good Luck.

    I have lubed up every moving part I can find. It still squeaks like a bunch of mice. I really just wnat to put a few hunderd more miles on it. I plan to switch back to running at the end of October and take the bike in for a complete tuneup. The hilly hundred is next weekend and I dont want my bike in the shop. what risks am i taking? Could something damamge the frame, the bottom bracked? is so would it be incredibly expensive if I ride it till it breaks. I guess I need to get at least 500 more miles on it.

    I had a squeak after 500 miles on my new road bike. I only heard it while pedaling. It seemed to be coming from either the BB or the pedals. It ended up being a dry rear derailer jockey pulley. I removed it and cleaned and greased it. No more squeak even after 1000 more miles.

    I took the bike out to the wrench today. The non drive side bearings were dirty and dry. He repacked the bearings and cleaned out the BB,sounds fine for a few hundred yards. I will take it out tommorw.
