make sure the hoses at the lever are connected good and tight. as others have said, pull mineral oil from the cup and push it back, slowly, repeatedly to expel air. lastly, remove the cup, reinstall the cup cap then undo the air bleed screw and push a little fluid until it oozes out. close that off and then close off the bleed outlet at the caliper. should bee good to go then.

I just want to acknowledge that this technique works very well! I struggled for months with a super spongy rear brake using Ltwoo RX levers and zrace flat mount calipers. The back and forth 10 times then overflowing the air bleed port did the trick. Thanks for the tip!

I went with the sid because it was a good deal. I got it used for like $120 and it's tuned for a Transition Spur which isn't ideal but so far it's been fine.

I popped into AliEx this morning and saw that many things I had in my cart for price tracking/future purchase had near doubled in price.

Yikes.  Wonder what established western brands pricing will do in the US in coming weeks if all this tariff stuff goes through.

I'm in the US and found the same situation. I just received a bad zrace xg caliper. Since they're giving me a refund I need to order a replacement and it went from $27 per caliper to $49 overnight! We're really showing them with these tariffs...

Can you fit 2.4s in the frame

I have a 2.4 Maxxis Dissector on the back and it seems to fit ok. Might be an issue in really thick mud but so far there's been plenty of clearance. For reference it does measure pretty much exactly 2.4".

Here's my bike finally fully assembled:
Frame: Large
Rear Shock: SideLuxe Ultimate
Fork: Fox 34 140mm
Seatpost: PNW Loam 150mm
Dropper Remote: Ztto
Saddle: Ryet 3d printed
Handlebar: ToSeek
Stem: ToSeek 70mm
Grips: ESI Chunky
Brakes: Ztto M1 X4/X2
Wheelset Ryet 33x30mm ratchet
Rotors: Sram Centerline
BB: Shimano XT
Crankset: Senicx FM2
Chainring: Zrace 32t
Pedals: XT
Cassette: Speedao 10-50t
Shifter: Sram GX Eagle
Rear Derailleur: Sram XO Eagle

I haven't weighed it while fully assembled but it should be around 12.5kg based on individual part weight.

Ride quality is pretty good. As previously state, the bearings are definitely garbage so those will need to be changed out shortly.

The black spacer. They're essentially the same measurement though.

Ah ok thank you.
And which length 35?

I also meant which Mountin Kit for the sid Lux because you also Need one so the Suspension does Not move left or Right
Best regards

From that link I used 22mm kit. The mounting bolt that came with the frame is 34mm in length.

Tomorrow I'll take a photo of the front without any problem.

I hope that when it arrives it doesn't happen to you like it did to me. They painted all the bearings, and I had to buy new ones and change them. I wrote to Rose complaining. I suppose that when they come back on vacation she will see it

Another thing that happened to me. The shock absorber shaft screw is 7.6mm and not 8mm, so it has a small, very minimal play. I have ordered other screws that measure 8 mm correctly. I have temporarily solved it by making a small cover.

If you have any questions, I will be happy to help you.

My shock bolt is also 7.6mm and has too much play. Do you have a link for an 8mm bolt?
