Well my truvativ firex cranks have been howling lately. Ive cleaned and lubed the BB numerous times and its kind of a grinding type creak as though the isis splines are popping or something. It feels and sounds as though its maybe my cranks trying to crack but ive inspected them and they seem okay. Ive got crank bolt washers in both sides and my BB apears to be in good condition. Ive only been on the bike for 6 months so I havent been all that hard on it? Does this sound like a BB or crank issue. I know its not all that specific but if you could just chime in thatd be great.
thanks
