I upgraded my SLX BB last year when it died after 2 solid years. I stuck an XTR one in there because it wasn't much more thinking it would wear better. After 4 months riding no more than once to twice a week on south downs it has developed a really bad cracking noise which after today is now 3 solid crunches per rotation, is this normal? Anyone else experienced this? Could it be something else? Or am I just unlucky?
Over with the questions
