    Bottom bracket maintenance...

    I have a 05 Stumpy FSR 120. Is there any maintenance to be done on the BB?

    Thanks

    What kind of BB is it? Some are sealed units others can be taken apart and regreased. How many miles do you have on it? Remove the cranks and see if it turns freely with out any gritty feeling. Is there any play in it?

    Not sure what BB is in it. Maybe 100 miles. Turns fine and smooth. Just trying to make things last as long as possible.

    I doubt you need maintenance after 100 miles unless you ride underwater. Did you remove the cranks to test if it turns smooth? You really need to know what kind of BB it is. There are many diferent kinds and they all work diferently and most take a special tool. Check out the park tools website. They have great how-to info on maintenance. Good luck

    what trim level is your stumpy?

    my wife's SJ120 Expert had the octalink cranks. the BB was a shimano unit. they are pretty well sealed and don't need any maint. unless you ride through deep water crossings.


    i actually have her stock octalink cranks and BB in a box in the garage. i got her some bling, XTR w/ external BB
