A couple years ago I worked probably 6 times thru the summer on a Synapse Disc Tiagra that was a raging POS. The bottom bracket/crankset clicked no matter what was done. It was a teen's bike who I train with thru the spring and summer and the bike shop couldnt get it to stop, neither could I. It was annoying to even ride with him, much less be the rider of that bike. I ended up giving a Shimano crankset to him and he had to buy a Wheels Mfg BB adapter. Noise was gone after that.
A metal bottom bracket shell should have threads. Simple as that.
Did you guys use the FSA tool to check if the the BB shell was still in specs? The only time my LBS says they've had issues that can't be fixed are when riders continue riding with the creak and elongated and ovalize the shell. Did you guys use 609 or 641 which fills larger gaps?
