But oil needle and olive head is bh90 right? Or also should be 59?

I use BH90 hose & barb with no issues.

I've used both, but I believe BH59 is what ships with LTwoo hydraulic shifters/calipers.

Some new videos from L-Twoo showing the new USB-C charging front derailleur. Given the videos perhaps it's getting closer to release?

I don't think I like USB-C charging. There are times when I forget I have the charger plugged in and yank the bike from the charging cable. Since it's magnetic, it just comes off. I thought they were going to use USB-C for the battery cables instead. It looks like they're still using the same accessory components.

Apparently the older LTwoo app software had auto-trim enabled, but they removed it most likely due to Shimano patents.

Can anyone hacked it back in ? :-D

From what I understood, it was optional. The rear derailleur still had the magnetic charging disconnect, but the FD had a usb-c just in case you preferred that. At least, that's how it was on the pre-release versions of the hardware. We can only hope it gets released like that in the final version.

Is there any way to reassign shifter buttons? I want to set the rear shifter to change into a harder gear with a small paddle and easier gear with a big one but it looks like you can only swap shifters between rd and fd in the app and nothing more

One of my ER9 groupsets just updated to ver. 0.1.7. adding TT button functionality. I guess the TT shifters will be available soon.

interesting. i'm on ver. 0.1.1 and the app tells me this is the newest version…

I have 2 ER9 groupsets and only one of them is getting the new firmware updates. I have no clue why LTwoo is updating only certain units and not all of them.

After taking off the LTWOO er9, I put on Sram Rival AXS and clocked the first 100k with it.
I’m using the exact same chain, cassette and chainrings. Rival shifts quieter overall on my setup. Front shifting is better. Never thought I’d say that of a Sram FD. Not having to trim the FD because of the yaw feature is nice. But I gotta say, it’s so close that most of it like ergonomics and Button Feedback is really a matter of taste.
Most of the things that Rival does better comes down to the software. Customisable Multi Shift. The fact that the groupset drops into the small ring if you cross chain too much. The way that the FD overshifts onto the big ring and waits for the chain to drop onto the small ring before it moves all the way in. That could easily be implemented by LTWOO as well but I reckon that patents prevent them from doing it.

As long as the barb matches the hose type, it's all good. So if you buy some BH90 replacement hose, get the BH90 barbs to go along with it. The rest is either the same or interchangeable.
