on my Felt AR5 I have an FSA gossamer crank with their 386bb.
For various reasons I'm looking to upgrade to an Ultegra crank.
Is it a question of removing the FSA bottom bracket and replacing with the Shimano one or is there more to it than that.
I don't think there is much else to it, I may be wrong without looking but you should be able to replace with a hollowtech BB once the Fsa one is out. Bear in mind the thread though, it's either English or Italian.
