Mikey-uk Posted September 12, 2009 Report Share Posted September 12, 2009 Heya, i was going to order a new left crank as it kept coming loose. I changed my mind however when i noticed i can wobble the bb around in the frame, i know this shouldn't happen and so i'm wondering if there is anyway of stopping this?Thanks Quote Link to comment Share on other sites More sharing options...

next doors cat Posted September 12, 2009 Report Share Posted September 12, 2009 (edited) I think i had a similar problem, the thread on the BB part of the frame wasnt quite machined properly which ment as i pedalled it unscrewed its self and came out, making it feel loose. you will have to take out your BB and take your crank off and have a reel good look at the thread inside the frame, on the bottom bracket and your crank to see whats what.Guy Edited September 12, 2009 by next doors cat Quote Link to comment Share on other sites More sharing options...
George.E Posted September 12, 2009 Report Share Posted September 12, 2009 You might have rounded off your crank arms.I would upgrade to ISIS Quote Link to comment Share on other sites More sharing options...
