Me vs Motobecane, ISIS, FSA and stupidity

I was getting a clicking sound from the Motobecane Le Champion SL. It was annoying, and getting worse. It sounded like it was coming from my FSA SL-K crankset/bottom bracket.

I did some research on Bikeforums.net and discover an "FSA click" thread. I also discovered ISIS style bottom brackets have a bad rep.

I took the bike to my local bike store and they said "Yep, it's the bottom bracket".

Rather than replace suspect bottom bracket with another ISIS, I ordered a Shimano R700 compact crank and Ultegra bottom bracket. I had the local store install both.

SIDENOTE. Bikesdirect speced "TruVativ or FSA" bottom bracket. This is what was found inside. It's marked "Chin Haur," whatever that means. The bike store says it wasn't installed very well.

ARRRGGGGG. It's was still clicking! But bikeforums.net "Substructure" said in a thread he tightened his QR and solved his problem

I really tightened my rear QR and zoom. All better. I am an idiot. But then my LBS didn't exactly save the day either. On the other hand, LBS had no problem with me finding a great deal on the cranks and BB elsewhere and having them install it all.

Did I waste money? Maybe, but the Ultegra shifts a bit better, and I'm pleased to not have that other BB any longer.

Such is life.

    yeah, badly attached BB for sure, next time, read the fkng manual how to put them on. Use lubrication and torque wrench... yeah I call that stupidity allright.
