Question about Shimano BB 86/386 crankset

Hello everyone,

I currently have a road bike (BB86 pressfit) with a FSA 386 crank and would like to replace it with a Shimano Ultegra crank (172.5mm vs 170mm). Based on internet research, I see a lot of folks using BB adapters (e.g. Wheels Mfg), instead of buying Shimano BB86 Bottom Bracket. Why is that? Wouldn't it make more sense to by a new BB instead of an adapter? Often, the adapters are more costly than the Shimano BB. Is this b/c of cost? I assume the cost of a LBS replacing the BB shouldn't be more than $50?

Thanks!

    BB86 is one of the better press fit standards - unless someone is determined to use an alternative/adaptor you shouldn't really need one if you are using a Shimano chainset.

    I don't really like those adaptors so I think it's a nicer solution to have a BB that takes your chainset without any additions.

    Shouldn't cost too much to have it installed.
    I'm left handed, if that matters.

    Shimano BB86 BB is really good.
