Will Shimano Ultegra swap with FSA MegaExo/Gossamer?
I've been struggling with a clicking/creaking noise on my 2010 Cannondale Synapse 5 Alloy for about two years. It has a MegaExo 6000 English 68 bottom bracket with the external cups and it's running an FSA Gossamer triple crankset.
Long story made very short, shops and private mechanics have tried to fix it to no avail. There is a really long list of what has been tried or ruled out and didn't stop the clicking. Most recently, I put in a new MegaExo 6000 bottom bracket and reinstalled the crankset in the proper sequence and properly torqued each bolt according the specs. The clicking/creaking was noticeable as soon as I left the driveway, maybe 50 feet. That's not enough space to have ruined a bearing with the proper torque and loading.
I'm down to wondering if it could be something in the crankset.
The frame is sized and threaded to take a MegaExo 6000 external cup bottom bracket. Can I swap that out for a Shimano BB6700 and swap the FSA Gossamer for a Shimano Ultegra FC-6700 triple crankset? Logically, the frame is sized and threaded for 68 English so one should be interchangeable with the other, right?
Thanks for any insight.
