Did you back off the tiny reach adjust screws in the brake levers when bleeding? They can push the master cilynder enough to block the oil flow when bleeding otherwise. You will still be able to push the oil through but with a lot of resistance and you won’t be able to get all the air out.

That was the issue, didn't know.. Saw it in the youtube video.
Thanks for the help guys.

Tsunami GR02, thats a good aluminum frame.


I second that. Mine was like $325 shipped to the US (11/11 sale). It's well made and the paint is excellent. It is a bit more of an all-road bike, but it's great on smooth gravel roads and rough pavement.

I run an XG on the back and a dura ace from EBay on the front—aero where it matters more

Why not go full Dura-ace front and rear?

Damn bleeding these brakes is a mess. Front brake failed to bleed multiple times.
Saw a 105 di2 group cheap around me and bought it. With all the fails, I'm gonna sell it and be safe :s

I like AliEx for little things like this.

FYI - the ZRace XG calipers have been working fine at least for road. Nothing wrong with LTwoo calipers and they might be better if aero is a priority, but since I focus more on climbing I prefer the weight drop of the XG calipers. I've been using them on both my mechanical Ultegra and ER9 bikes with no problems so far.

For me, it's actually quite the opposite. I have easier time bleeding the calipers, especially with the additional air port. I very much prefer L-Twoo's system compared to previous 11 speed Shimano. I haven't tried the new 12 speed system from Shimano, but I'd guess it's similar.

Agree, I've bled both Shimano 11-speed 105 (R7020/R7070) and L-TWOO eR9. I found L-TWOO to be easier, the threaded bleed port on the calipers results in less mess.

Check if the olive was properly crushed? It was my first time doing it and it went very smoothly for me.
