Shimano drivetrain compatibility

Do you have the corresponding xtr/deore derailleurs (M9000 and M5100)? What are the current cassettes on the bikes? I don't think the xtr derailleur will comfortably clear a 51 cog but it can do 46 assuming it's a 1x drivetrain. Best bet would be to get a 11-46 cassette. To swap out a cassette and chain you need a cassette removal tool, a chain whip and assuming the chains have a quick/master link, some master link chain pliers. Best to also have a chain breaker so you can size new chains appropriately.

However, are both bikes at the LBS? I don't quite follow why you need a spare cassette and chain between two bikes?

I'll have to see which xtr derailleur I have, didnt realize there was more than one kind. Only the giant is at the bike shop but I'm wanting to buy spares so I can repair the bikes myself. Also I'd like to buy a set of wheels that will work for both bikes but really I want to lighten up the Giant a little but. Ideally one cassette would work on both bikes.

if You want a 12 speed cassette, you’ll have to go full 12 speed: free hub, cranks, chainring, derailleur, shifter....

It will be much easier financially to go 1x11.

I'm definitely staying with 11 spd, both bikes are 11 spd currently.

Then you can’t have a 10-51.

I think e13 makes a 9-46 11 speed cassette in 11 speed

I mistyped, one bike is 11-46 and the other is 11-51.

Just checked it out...its $230. Is this a superior product to shimano?

My Shimano 12 speed shifts well (for a 12 speed). If I were you, I’d get an SLX or XT.

Will a shimano cs-m8000 cassette work with m5100 deore and m9000 Xtr derailleurs?

I don’t know from experience, but I would place a large bet that it does. i‘m almost certain that the only real difference is the makeup of the part and not how the part will operate across the Shimano lines.

I picked up my bike at the LBS today and that's the cassette they used. Its a XT cassette, they think xt is the sweet spot between weight, cost, and durability. They confirmed it would work on deore 11spd too.
