It could be your chain ring or spider moving at the top dead cente rotation point, your chain ring bolts (if you have them), your pedals and as a last resort could be your freewheel or bearings in the your rear hub (a bearing may have splintered).  :daumenhoch:


Better to crash and burn than fade away

i think the inner spacer has to be spot on.
-if you can feel it wiggling about with the bearings tigh in the bb shell
-then you can assume the arms are pulling the bearings apart when you tighten

I done 3 euro bb's in the last year  :idiot2: My latest one has just started creaking too  :tickedoff: wish i didnt go for this euro frame now  :(

Not sure if its coz of the quality (wethepeople and 2 fit bb's) maybe have to spend a big wodge to get something thats not going to go bang every few months  :knuppel2:

Hmmm, I ran the same euro BB (came with a generix crank set from OT's) from July '04 without trouble, have just changed (last month) to a Primo Euro BB and also no trouble.
