Grovesy93 Posted July 23, 2010 Report Share Posted July 23, 2010 Hey guys, recently my BB seems to have "slipped" now making my left hand crank rub on the frame. I dont know how to fix the issue so some help would really be needed as it is really affecting my riding at the moment. And on a similar issue both cranks wobble from side to side I dont know if this is related or not. Thanks in advance Sean Quote Link to comment Share on other sites More sharing options...

Thanks in advance Sean I have no idea how it could have slipped but if the cranks are wobbly then tighten up the bolts if you haven't done so already.

More than likely the bearings are gone/going or its stripped. If its hitting the frame it could be where they are flexing inwards due to the wobbling of the bb.

Sam Styles Posted July 23, 2010 Report Share Posted July 23, 2010 ive just put a new bb in today because my old bb spacers worn down, leaving a groove in the spacers, allowing the cranks to wobble and be at an angle... take the arms off and have a look at the spacers. would be helpfull though knowing what bb it is Quote Link to comment Share on other sites More sharing options...
that NBR dude Posted July 23, 2010 Report Share Posted July 23, 2010 Check your BB is actually screwed in tight and hasnt been unscrewing itself. If your BB has unscrewed slightly, this could be why your left crank is now touching the frame. Quote Link to comment Share on other sites More sharing options...
Grovesy93 Posted July 23, 2010 Author Report Share Posted July 23, 2010 Thanks for the replies, the bb is the onza square taper (I think, well its the standard one that comes with the onza comp 09) I will check that the spacers arent gone and that the BB is tight. The crank arms are tight so I know its not that Cheers Sean Quote Link to comment Share on other sites More sharing options...
