Hello everybody! I have a 2005 Norco Havoc and have a cracking noise coming from it. I have tightened the cranks to 300 lbs tourque but still never helped the cracking noise. I was thinking that maybe my bottom bracket needs to be tightened. But I have a problem. What tool should I use? It would be nice to check on e-bay to see if there is any there that could help me! Thanks alot!!!!
