Shimano xt deore groupset

[Jeorje]

Hi all ..upgraded my bike ...Giant anthem 2016 to a 1 x  11 ...this ring or spacer keeps getting eaten away after a few rides ...maybe 10 or 20 rides...my bike starts with a progressive grating noise ...took it back to bikeshop that fitted the first time....now noise starting again so I stripped to find the same problem...any advice please?

Which side is this thing, drive-side or non? I've built a few bikes and have yet to encounter one

[Jeorje]

It's a spacer in the cassette

Isn't that for a 12 speed cassette? Hence the 8(1)10 designation? I thought 11 speed is a 8(0)00 type code? 

Like 8100 is slx 12 speed code, isn't 8110 xt 12 speed?

That part is causing lots of issues as its one of the causes for a creaking shimano rear hub. It also has to be installed correctly. Go on youtube and search for creaking shimano rear hub.

The part the OP is referring to is the microspline spacer found on the Simano 12-speed freehub body. 

Initially Shimano recommended not greasing the part the spacer sits on - see page 14 of the attached (marked as part G). This was updated to a premium grease (Y04110000) to be applied - see pages 17 & 18. 

If you're LBS is not aware of this or does not have the special grease find a new LBS

Is your hub correct for a 12sp cassette?

Isn't that spacer specific to a micro spline freebody?

[Jeorje]

I do recall them having to change the rear hub to a shimano FH-M8110 .When you refer to micro spline would this be correct? 

[Jeorje]

Another thing is when I free wheel since the upgrade my bike is silent 

[DieselnDust]

Is this the spacer that’s used when running the 12 speed shifter in 11speed mode with a compatible 11speed cassette?

if yes then shouldn’t it be removed when used with a 12speed cassette?

[Jeorje]

So after a Google search I see it all looks correct for a 12 speed and its a micro spline
