Shimano xt 8100

Has anyone used this drivetrain? Is the ‘better shifting under power’ real or bs? I would think the much higher chain tension on an ebike would just accelerate wear if you shift under power

I have no clue about any shift under power. I think with all the shifting i have done the habit is there. I will never do that.

Me too! I have too much mechanical sympathy to ever shift under power. I believe that I'd fall off my bike or stall before shifting under power.

Shifting under load with the M9100 worked very well. Single shifting. My expectations are high for the M8100 and M7100 shifting performance.

‘better shifting under power’

Can't say I've read any such official claim from Shimano about the groupset anywhere. I spent an hour talking with a Shimano rep the day it was released to dealers. There was no mention of such a claim then either.
Before calling "BS". Where exactly have you read this statement?

There was also a vid by Shimano USA where their rep (guy with bushy brown hair and beard) said it was even better on ebikes.

Shimano wrote precisely NONE of those words

Do you think all those different sources made up the same words coincidentally? Or is it all fake news? Or would you discount shimano’s own words as marketing clickbait?

Here is Shimano USA saying it

MAKE IT STOOOOOOOP!!!

Still not reading (or hearing) any official Shimano claim of

‘better shifting under power’

other than from YOU

"under tension" is not the same thing as "under power"
