    sound coming out of the BB....

    Ok, after a few hard rides, my bike started making a sound again... it went away after the first tune up.

    basically, the sound is a "clank" that happens when, standing on the pedals, if I put the left pedal down, then apply pressure to it, then if I switch back to the right, the right one does it. i imagine its a loose BB? I can picture the thing swiveling of sorts every time pressure is applied to either side... could that be in?

    Thanks!
    SOK

    PS: is this normal stuff that happens to entry bikes? i have a 4300.

    You can check for a loose BB by holding both arms and moving them towards and away from each other. If there is any play at all, it needs to be tightened. I think the 4300 has square taper BB so make sure you check that the arms are bolted on tight as well.

    sounds like you need a new BB or there was an install failure. How old is the bike/miles?
