Problems with FSA K-Force crankset

I have this crankset on my bike. It has the MegaExo BB system. Lately it has been making a "knocking" and "grinding" noise.I took it in to the LBS and the mechanic there says that the BB is "junk"! He also told me that because of the design of the crankset the problem will occur again if I replace the BB. His advice to me is to replace the FSA carbon crankset with Dura-Ace as Shimano has a much better design. I really like this crankset and I would like to continue using if possible. Any advice or info. that anyone might have would be greatly appreciated.

Send your BB cups to Enduro and they will R&R your bearings for the cost of the bearings+return shipping.
Ask for Chris.

I've no personal experience, but this sounds like it could be the kind of BS that mechanics spout from time to time. Isn't this the BB that Team CSC use? How many km did you get before failure? I would try the same BB again before giving up.
I vaguely recall that you can use a Shimano Hollowtech II BB with FSA chainsets. Anyone know?

If you're adventurous, you could pull the crank off, yourself, pop the friction cover off of each bearing cup, carefully pry out the seals from each bearing, and check to see if the bearings were greased. If you find that they are "dry", pack them with some grease, and then reverse the process to get the crank back together.

Make sure you put a coating of grease all around the lip of the bearing cup where the seal is "captured" underneath--to help keep contaminants out.

I use FSA Team Issue cranks with Shimano Octalink bb. I installed them myself with little experience. That was back in 2005. No problems to date. I use mine cupled with Shimano Ultegra 10 speed.

Hope it is helpful

The Octalink BBs are pretty much sealed. The MegaExo is an outboard bearing set utilizing cartridge bearings (like Shimano's Hollowtech II), which is what may have biased the mechanic. He may not like outboard bearings. Or, maybe he's a Campy fan. Just guessing, of course.

If this is true, he'd better retire fast, or get with the plan. Doesn't Campy Ultra-Torque (silly name, does it have a little motor in it?) use outboard bearings?
