Which Shimano or (FSA) chainset will fit a pressfit bottom bracket which is not a BB30. ( I know FSA Mega is external so will never go with pressfit or 30 BB) With my little understanding I guess that any Shimano will go to pressfit type like all the pressfit bike as Scott, TCR, Wilier Cento, ect... But I need to be sure.
Your help is needed.

Any, just get the correct bb86 or bb90 bottom bracket. I have a fsa Bb86 in mine with a 6700 crankset.

All fsa and all shimano will work, most SRAM except bb30 too.

Thanks that's what I thought. Also do you know if it is the same rule for Rotor?

Would you know to tell if it will work as well with the Ultegra 6600 and 6600 SL chainset?
Thanks

Rotor 3d is 24mm spindle, 3d+ is 30mm. if its not press fit the you can use their enlarged external bearings to fit the 3d+.

but the 3d will fit in a BB86

I have better question which might help me to get what I am looking for

Which bottom bracket press fit type (if exist) is needed for a FSA chainset to be installed on BB90 shell?
I know FSA has a pressfit BB386 but I guess it is a different frame's shell than BB90 frame's shell.

as long as it's their k-force light or sl-k light crank, this is what you need

Thanks for that it's very helpful. That means inside my frame shell which is computable SM BB91 from Shimano I can install these bearings you suggested if I want to use the K Force or SL-K Light from FSA, is that correct?

also I read in the competitive cyclist that the BB AL90 version only with works with the gossamer cranks but not with their carbon cranks as the k-force and the SL-k is carbon. Any suggestion?
