Need Help Replacing Shimano BB with FSA BB

I recently purchased an FSA Gossamer 50/34 Crank to use in replacement of my existing Ultegra 53/39. On reading the installation instructions, FSA says I need to use a BB Removal tool #E0019. I read elsewhere that I need a Park BB Tool BB-9. Am I missing something, or with these two tools can I remove and replace the BB? I guess I also need a Circlip removal too as well. I viewed a few online tutorials, but the ones I found didn't cover the exact same configurations that I have - your help and advice is really appreciated.

If you take your crank out, you can hold the FSA cup next to the Shimano cup, and see if the 'notches' line up. If they do, the same tool will work for both. If they do not, then you'll need a tool for each one.

What frame do you have? The BBT9 is used to remove external bb cups, such as what is used on Shimano 5600, 6600, 6700, and 7900-series. The E0019 is a tool used to tap out the bb bearings on a BB30 crankset. If you bought an FSA BB30 crankset and don't have a BB30 shell on your frame, there lies your problem.

The FSA gossamer is compatible with the ultegra BB (at least ultegra BBs made for the hollowtech ii cranks like the Ultegra 6700). I am running that setup right now. So you probably don't need to replace the BB unless you have to for other reasons.

This depends on which Gossamer compact the OP purchased: MegaExo or BB30. If it's the latter, and the OP's frame doesn't have a BB30 shell, then the FSA crank is incompatible. Since he referenced the need for the E0019 tool and circlip pliers, I assumed he has the BB30 version. However, my assumption may be wrong; the last sentence of the first post suggests that he may just be looking at the wrong online installation guide.

I have the FSA Mega Exo BB-6000 (see the attached photos). Currently on my bike I have Ultegra FC-6600 Hollowtech II cranks, and assume that the Shimano BB is Ultegra (since I haven't removed it I can't see the model no.) photos are attached.



After looking at the Parktool Website, it seems that if these two BB's are compatible, I may be able to use a Parktool BBT-9 to remove and replace the BB; is that correct? What still confuses me is what tool(s) I need to remove and replace the bearings? Thanks for all your assistance!!

Okay, you must have been looking at the instructions for the BB30 version. You won't have any need for the circlip pliers or E0019 tool. The BBT9 will work on both bottom brackets. The Park BBT-19 is another option which, unlike the BBT9, will allow you to use a torque wrench. Shimano offers their similar TL-FC33 which appears to be the best of the available choices (I have the BBT9 but will replace with the latter if the need arises). If you do get either the BBT-19 or TLFC33, you'll need to drop another $3 on the TLFC16 (or similar 8-notch tool) for the Hollowtech preload screw.

BUT, if you're current Shimano BB is in good condition, you may wish to just leave it in place. Though I haven't used an FSA crank, my understanding is that the Shimano BB will work with aluminum MegaExo cranks. Some users state that Shimano's BB is "better" than the MegaExo.

Oh, the bearing cartridges are pressed into the cups. You only need the tool to remove the cups from the shell; you don't remove the bearings separately.

That's great news! If I decide at some point to remove the bearings from the cups, do you happen to know which tool I'll need?
