Has anyone bought the new version of these?
The master cylinder was moved inside and pistons are now ceramic.
They look sleek!

isnt that just onirii br-05 rebadged?
if it is, i ran it on my tt912, n brake power is adequate for me on 140/140 setup with mt-rt900 rotors

Looks like an updated version of the br-05. I think the br-05 doesn't come with ceramic pistons.

this is my onirii br-05 recently bought for my ttx38 build.
im not sure if thats ceramic piston.

i havent open my tt912 br-05, but i'd assume theyre the same, as the price about the same bought during sales of CnY vs 11.11 last year

Yeap those are ceramic too so you must be right they must be identical.

How do they compare to hydraulic?

[ejump0]

unfortunately i never had experience with full hydro

my experiences:
- Gusto RCR with old gen sram force rim rental bike
- TCR with mech 105r7000 sti + Giant Conduct hybrid hydraulic brakes on 140/140 rotors
- Tri bike with onirii br-05 with tektro tl720 levers with jagwire keb-sl cables, 140/140 rt-mt900 rotors.

Brake wise the br-05 is on par with giant conduct for brake power and modulation (but take note the brake levers are different), way better than rim (the bite is exponential despite mechanical pull).
im in the process building my ttx38 with sensah reflex(2x8) sti's, so i'll get back once tested the modulation
/why 2x8 levers? because my RD is axs, so im using sram wr-blips to shift
