Quick roadie question. I have an FSA Gossamer chainset on my road bike with a FSA Mega Exo bottom bracket that is getting a bit grumbly. I have 2 spanking new Shimano Ultegra BB's, do you know if they are compatible. Width's look the same and if you look at, say a Hope aftermarket BB they say its compatible withs Simano, FSA etc which makes me think they must be all the same dimensions, crank spindle diameter seems bob on.
Cheers

As far as I know Shimano and FSA are compatible.
Same logic as you have applied, both work with CK BBs so must be same size...
Will be fine, popped a 105 one in a cross bike a few weeks ago due to the obscene cost of an FSA bottom bracket.
Alloy cranks are Shimano compatible. The Carbon ones need the special mega exo version.
Cheers chaps, They are alloy cranks, save me a few quid and I also have a spare!
