I will confirm when I can but I’m sure it’s the m4100 Deore 10 speed
Is that for the shifter?I will confirm when I can but I’m sure it’s the m4100 Deore 10 speed
No.Do you think shortening my current chain to the shortest possible length will
Fully agree,No.
Your chain length should be set at the shortest length in your largest rear sprocket with the swing arm at the point of max chain growth.
Using a smaller range cassette means the chain can be shorter.
Chain wrap (how much chain is in contact with the sprocket) is increased from running a smaller range cassette and being able to run the top jockey wheel much closer to the small sprockets (b-tension adjustment)
You have already said you don't want to run a smaller range (11-36) cassette
From the PM you sent telling me you're a "Derestricted aggressive downhill rider who gives it large on the cranks in the smallest sprockets" I suspect your premature sprocket wear may actually be down to your riding style and shifting under load. If this is the case the best way you can increase cassette life is to learn how to ease off and shift smoothly and stop shifting under load.
I'm assuming you understand the mechanics of a derailleur system including b-tension here.
I can see a few options of 10spd 11-42 cassetes.Your Freehub will take any 8,9,10 or 11speed HG cassette. Only an old 7 speed cassette would need a spacer.
Whatever mech you choose to buy. Also buy the corresponding speed shifter from the same manufacturer. And a corresponding sped chain. But this doesn't have to be from the same manufacturer. Infact I always use sram chains on Shimano cassettes.

SHIMANO DEORE - Rear Derailleur RD-M5120-SGS
Thats what I am using
The M5120 derailleur looks the same as the M4120.
do you know the difference? I can see that possibly the M4120 only works up to 42T.
Can you advise why you chose that derailleur as I’m struggling to find it anywhere.
Can I ask why you didn’t go for the M6000?These new cassettes come with two new rear derailleur options: the M5120 (which has a clutch) is designed for use with 42-46T cassettes, while the M4120 (no clutch) has a maximum cog limit of 42T.
M6000 11-42 largest sprocket is made from aluminiumI can see a few options of 10spd 11-42 cassetes.
is m4100 the one I want?
I’m referring to the m6000 derailleur sorry.M6000 11-42 largest sprocket is made from aluminium
I wouldn't even considering a cassette with an aluminium sprocket if greater longevity is your main reason for changing
Morning Gary,M6000 11-42 largest sprocket is made from aluminium

Much appreciated. I had presumed but wanted to confirm.If you can't work it out, You need the GS medium cage version for a 42t cassette sprocket.
Chainring size difference is irrelevant as you only have one chainring.
Capacity is just how much slack the mech can take up. Ie 11-42 =31t
Is the below chain ring compatible with a 10 speed chain?If you can't work it out, You need the GS medium cage version for a 42t cassette sprocket.

Depends on riding type.Is this an issue?
So little time will be spent on the 42, longevity of that aluminium ring I suspect is not going to be an issue relative to the rest of the cassette.
You want the medium cage@Gary and @ everyone .. so I decided to prepare for the ex1 less future. Here's what I've assembled:
M8000 sgs long cage derailleur. Clutch adjusted correctly.
2. Dyna sys 11 rdm8000 new jockey wheels $24
3. Deore cs m4100 11-46 10 speed cassette new $50
4. Deore 10 speed shifter slm6000-r $28
5. 11 speed can hg 70-11 chain ( already owned 2 of these new in box.
So I've invested about $100 in this drive train but will wait for my ex1 to fully wear out before using this stuff.
Opinions???
Agreed, more robust.Why are you choosing to use an 11spd chain with a 10speed drivetrain?
It will work. But a 10speed chain is better suited.
A SRAM 1030 at around a tenner would be my choice.
Are you after ex1 SamDo you still have the ex1?
That's not the reason it's better suited.more robust.
Do 10 speed chains not also have thicker side plates between links?That's not the reason it's better suited.
11 speed chains are 0.2mm narrower and will cause slighty less efficient shifting when used with a 10 speed cassette
