Shimano Triple MTB Crank in BB86 Frame???

Hello

Been googling like mad to get an answer to this without success.

My very stubborn old dad has been given a a Frame with a BB86 bottom bracket and insists he wants a Shimano 44-32-22 MTB
Hollowtech II Chainset in it.

I thought the solution to this was staightforward - put a Shimana Pressfit MTB BB in , namely

But looking a bit deeper at this, it appears that these BB's are for BB89.5(whatever that is ) and BB92.

It seems that if you have a frame with a BB86 Shell you can only put Road chainsets in.

Am i right or am i missing something - i think the latter will be correct btw

Any help would be appreciated

Thanks

This might help. HTII and square taper I understand, but all the other numbers are just confusing.

Thanks for the response but cooldad but not what i'm looking for unfortunately.

Anyone else any idea how to run a Shimano 44-32-22 MTB Chainset in a frame with a BB86 bottom bracket bearing in mind that the solution i thought to this was to put a Shimana Pressfit MTB BB in -

appears to be incorrect because this requires a BB89.5 or BB92 width Bottom Bracket Shell
