[Closed] shimano xt m8000 chainset.......is it 'boost'?

Not unless it is specifically advertised as one. There are two. The normal m8000 and m8000 boost.

and looking at mine......there is no way of telling if it is or not.... 😡

Do you still have the box? (notice the FC-M8000-B checkmark)

Also, should be on the crankarm itself:

So long as you have chainstay clearance it doesn't really matter, just means your chainring is 1.5mm further inboard.

In all honesty I think a non boost chainset on a boost frame can actually improve chainline if you are running a dinner plate cassette as it lines it up more with the massive chainrings.

You can always add spacers under the chainring on the Boost one, but you can't avoid the chain rubbing on the rear tyre with the non-Boost :).

just checked.....it is boost. thanks for the info gents.
