    *Click* in my cranks/bottom bracket.

    Hey,

    I have a 3 week old bike, and I've noticed some faint clicking in my bottom bracket when I pedal. Could this be the chain? Could it be the bottom bracket? I'm just concerned, since the bike is so new (and was set up at a bike shop) and didn't know if this was normal. It stops when I don't pedal (its a single speed).

    if the click is once per revolution it could be: pedals, chainring bolts, crankarm bolts, or bottom bracket. i usually check in that order.

    i recently had a 'click' i noticed it would only click when i applied pressure on the downward/forward part of my stroke. i did a search here and found out it could be a number of things.

    loose chainring nut, loose crank arms, BB problems and one final one.

    -> dirt/crap in my pedal to crank arm threading from riding in the raid a few days earlier. wiped em off, screwed em back in, problem fixed @_@.

    suggestions for your problem. if you think its the chain, take it off. spin the cranks. still hear it?
    if not checkin order pedals, crank arms, chainring bolts. if all else fails then have a look at your BB


    edit: i type too slow bah!

    Probably the chainring needs to be tightened?

    Most chain ring bolts are are aluminum. On one of my first fixed bikes I would break one or two aluminum bolts per week. Then I got hip to the "track" chain ring bolts which are steel. Never broke one since.

    So, if you have to replace the bolts, spend the extra $5 and get the steel ones.

    I had creaks in my BB, and I took it out, cleaned it (the amount of AL that came off the threads were amazing - the mineral spirits I used looked like silver paint), and reinstalled it - and the sound went away. I swear the bike is easier to ride too (it's my road bike), but that's probably in my head.

    i get a clicking in my bottom bracket whenever i pedal hard. it feels like its coming from my right pedal. i checked my pedals, chain ring bolts, took off and regreased my right crank, but it steals clicks when i pedal hard, usually at the top of my pedal stroke as i push down. im guessing i have to clean and regrease my bottom bracket? if so, how do i take it out. it doesnt have a lockring, its an old shimano botom bracket on a nishiki frame. is there a special tool i have to buy?

    possible that your cranks a little lose, i've commonly had a little creaking and cracking after some light rain or enough rain to get the spindle wet.

    I think sheldon brown would then advise that you bring your bicycle to a shop

    edit: I wonder if sheldon even has this forum on monitoring anymore. We must trip his searchbot like every 4 threads.
