    Speed P8 Bottom Bracket Replacement

    I've posted about this problem before with a clicking problem on the bottom bracket.
    The BB specs;

    Chin Haur
    CH51-68
    113.5L
    BC1.37 - 24T

    It turns out, the clicking was NOT the bearings but the housing. The housing is not
    a one piece construction like most bottom brackets but a 2 pieces pressed together.
    The problem is, the pieces became loose and separated.

    I finally replaced it with a Shimano 115mm shaft BB and it seems to work pretty well.

    Chin Haur B.B. is crap

    I,too, have replaced the Chin Haur bb on my two Dahons. They are crap! I used a much shorter spindle.
