Hello, is a reducer included because of the smaller diameter of the nuts?

Hello,
The reducer is not included in the package. As an alternative, you can use this puller:

Hello, with this bottom bracket MT - 800 I want to replace the existing BB 52. From previous questions I understood that it’s not a problem. I just want to ask whether the installation adapter is included in the MT-800 bottom bracket package?

Hello,

thank you for your question. The manufacturer has stopped including this adapter with the bottom bracket, so it needs to be purchased separately: https://www.koloshop.cz/cs/Shimano-TL-FC25-klic-na-stredove-slozeni-SM-BBR60-MT800/116304?v=224739

Can I use this bottom bracket for Shimano XT FC-M782 cranks or do I have to use SM-BB52?

Hello,

you can also use the newer MT800, it will fit as well.

Ondřej Technical Support

Hello, on my bike I have a SH-BB51 bottom bracket. Can I replace it with this XT BB-MT800? I expect it to be higher quality. Or is SM-BB52 more than enough? Will BB-MT800 fit? What is the “adapter” in the package for? Thanks, Honza

Hello, BB52 is a direct replacement for BB51 and is basically the same. MT800 will be higher quality and look better; they have a smaller outer dimension. The adapter is exactly because of the smaller outer diameter of the cups so they can be tightened with a standard tool like the older cups.
