Bottom Bracket Replacement MegaExo BB-6200
I just wanted to confirm that I can switch out my FSA MegaExo BB-6200 with a Shimano Ultegra 6700 BB. My BB is starting to make a clicking noise, and my crank fell off (because I forgot to tighten down the screw I guess), plus it's been about 3 years.

It may work, but MegaExo and HT2 aren't 100% compatible, but are close enough (you can google for all the yes it will, no it won't arguements)
For the BB 6700, This is a long OOP part, you should be looking at a BBR60 now.

Got it! Been reading old threads so I'm guessing BBR60 didn't exist then. I've read that you just have to use a bit of force to get the cranks on the Shimano BB.

From an old post of mine:
I wonder about the FSA/Shimano compatibility.
I just swapped a FSA crank from my 2009 Kona Unit with a SLX from another bike.
My intention was just to swap cranksets.
When I tried to install the FSA in the other bike with the SLX bottom bracket, it was tight going through the first bearing, had to use a dead blow hammer just a bit. However, when I went to seat the crankset fully in the bearings, I couldn't do it. I used the dead blow hammer but it wouldn't fully seat, at least 1/4" of shaft still out of the bearing - I was afraid to do it too much in case I wouldn't be able to get it back out.
I should have checked with my calipers but just swapped bottom brackets. Everything went together easy after I did that.
And yes, the bottom bracket had been faced and chased. Wonder if it was just tolerance stacking or if there is a slight difference.
And from someone else's post:
Shimano runs a -0/+.xxx tolerance and FSA is the reverse. If your lucky they will work together but more often than not they clash.

Sweet, thank you. Is it necessary to face and chase the BB threads? Trying to see if it's worth my money to invest in the tools, but the costs are adding up fast. My local store will replace the BB for $30.
On the bright side, it seems like my BB is okay after all, I just needed to tighten down the crank bolt. But I still want to do this swap in the future.
