If you used a hose on it you may have driven contaminants past seals or just got grit into some moving part?
It did turn out to be the bottom bracket. I have a 07 Cannondale Prophet 5. Would like to get a BB that wont go bad in 5 months. It came with a TruVatiV ISIS GigaPipe SL. Any suggestions?
Rigt now I am leaning towards an 08 XT
You are leaning in the right direction
