Are you using a front derailleur? If not, get a narrow/wide ring.
If so, yes but... The curved inner tabs on those XT rings don't play nice with all cranks and may require some filing.

Or get an SLX version for simpler fitment.

Hey team,

Just changed to a 30T and new chain on my GX Eagle drivetrain and am now getting some serious "jumping" under load. It's fine on a steady cadence, it's just when you stomp on it. It's missing on the same gear, not jumping between gears. Cassette is just over 2 years old. Thoughts ?

Your cassette is fucked.

I ordered the SLX one thanks

I have a bike with 180mm front and 160mm rear post mount discs as standard. I want to go to 203mm front 180mm rear, but unclear about what adaptors I will need?

If theres currently no adaptors under the calipers, you'll need a post mount +20mm for the rear and +23mm for the front. Shimano offer them (if you can find stock) hayes and hope also offer them too. Theirs are less faff but pricier than shimano.

Thanks, yeah I found this info off Pinkbike

Shimano PM adapters....
SM-MA-F180P/P2 = 20mm
SM-MA-F203P/PM = 23mm
SM-MA-F203P/P = 43mm

140mm post mount + SM-MA-F180P/P2 = 160mm rotor
160mm post mount + SM-MA-F180P/P2 = 180mm rotor
160mm post mount + SM-MA-F203P/P = 203mm rotor
180mm post mount + SM-MA-F203P/PM = 203mm rotor

180mm post mount & sram +40mm = 220mm rotor

Long shot given the tumbleweeds here.. is the cable clamp bolt on an Eagle SX rear derailleur 4.5mm?? A 5mm key doesn't fit and a 4mm sort of flops around.

Also whats the deal with trying to get all the gears to index on SRAM 12 speed. Demon incantations?

Yeah. Getting the B tension and chain length perfect helps though. It's very picky. Read the manual for details. SX is particularly crap, it won't stay aligned for long.

Given the shite bolts that came with the codes I had, I expect flopping around is the intended behaviour.

Very picky. Spent ages on it today, checked my mech hanger alignment, got my B screw setup right as I can following the vids, I think I might only have one skipping gear now, I'll take that as a win.

This is the 15mm through axle on the front of my bike.
Is it unusual? I have googled 15mmm through axles and they all look quite different and have a threaded end, can't seem to find one like it.

Edit: OK found out it's a Suntour Q-Loc. Works quite well, nice and fast to take off at least.

Which fork?
I'm contemplating a Durolux, any review thoughts welcomed.

how dumb an idea is it to build a wheel out of 24 hole hub and a 32 hole rim?

i have built a spoke length calculator that will give em the correct lengths in excel. I'm guessing tension is going to be a problem (4 different lengths). anything else?

why you ask, my 32 hole hub is getting replace partially under warranty and it is taking a while. when it get it back i may put a carbon rim on it (from lite bike (26" baby))

the rim on my 24 spoke hub has split (where the braking surface would be if it was not disk). so i have 24 hub and 32 rim with some spokes i could have a new wheel till i get my hub back?
