wow. new thread. time to get back on the bike again. long time no ride. getting fatter. 

I really only ride in Kiara anyways.

And finally can test out the new (old) toy. Took a while to get it resized and sent back to me.

This is coil rear shock. Once you go coil, you never go back to air. 

What rear shock u got and for what bike?

Air fork will be good but I want a coil fork too.

What is your current group set?
what group set you wish to upgrade?

Looking at the pic... I think better to get a preloved rear wheelset(or better both) rather than changing the rear hubs... less hassle plus probably cheaper?

And on top of that... judging by the type of mtb and tourney groupset... you will need to change the BB as well.

Yes. you can go ahead to upgrade XTR but still I mention before you need change 12 speeds rear hub.

That seller just sell :

- SL-M9100 Shift Lever 1x12-Speed
- RD-M9100 Rear Derailleur SGS
- FC-M9120-2 Crankset (32T 34T 170MM 175MM)
- SM-BB93 (BSA 68/73mm) Swirling type
- CS-M9100 Cassette Sprocket (10-51T)
- CN-HG-M9100 chain 116L
- BR-M9100 Brake

Which you unable to make it.

you want buy from this seller err? He only got XT 12 speeds hub for you.

since you are aiming for whole group set and willing to spend on the most high end component, I suggest you direct go to famous bike shop order retail version XTR group set rather than those OEM version.

You can order XTR RIM set as well. Then it is complete XTR M9000 series. If order retail version come with so call warranty issue by Shimano Malaysia.

Sounds like quite a lot of money spent on this mtb... why not just straight get a trail worthy bike with decent groupset?

LOL.. full XTR group set for full suspension MTB complete branded bike non of them less than RM13k.

I saw his MTB is full suspension foldable bike so I guess if he want to buy new bike also will aim full sus. That one is really costly.

Lucky the hub converter is cheap. Rm20 can settle. LOL

actually tourney 8 speeds group set very nice. Your tourney  shifter is easy fire shifter?

In this price range really impeccable. Non of other competitor can beat it. Can share with us why you need to jump ship to XTR group set?

what is that mean?

smallest cog unable to reach or ?

The RD may be already end of life. It is due to rust or the spring issue. Just replace it with 8 speeds altus or acera or old model Alivio RD enough. That one below Rm90~Rm70 can settle.

I would usually think it's the H L screws not adjusted properly but since it's been tinker around, probably bend RD hanger or faulty RD?
