LTWOO ER9 & ERX - Electronic groepsets

[jonathanf2]

are the ergonomics of the EGR and ER9 brifters the same? Like can I just get an EGR right shifter and it'l feel the same like my left ER9? hahahaha

The EGR shift levers are just slightly longer. The difference is barely noticeable (maybe 1cm), but you can feel it when riding the drops. The EGR shift buttons require more pressure to shift as well. They feel/sound more clicky. They are different enough they might be awkward mis-matching them with ER9 levers.

Good to know... I just shot a DM to 80 Designer Store to see if they have any solutions. Temperatures are starting to rise again out here but i'd rather not have to face this again next year.

FYI, the eGR shifter is likely not immune to this issue, entirely. I've had issues with my right shifter (i.e. the only shifter I use since the eGR is 1x) being quite sticky. One of my buttons feels like it no longer has much spring back on the lever. It feels, to my finger feel, like most of the return force comes from the button itself. The lever frequently gets stuck near the button, but it's not really a problem because the button doesn't actually get stuck - it's just that the lever doesn't fully return to where my finger expects it.

Maybe the difference is that the eGR has a much more tactile and "clicky" button under the lever, so the button itself is just a little better at pushing the lever back. That's what it feels like to me.

Last year when I had the issue it was like you described where the button didn't spring back into the original position. This year since I've opened it up and stretch the spring like Trace Velo, the button returns but it still thinks it's being pushed. Something is contracting under the cold temperatures keeping it stuck and it happens at freezing temps seems like. Yea we'll see what 80DesignerStore and Ltwoo says. Responses are probably going to be a little slow seeing as it's Chinese New Year right now but I'll keep ya'll posted as I get updates...

80 Designer Store has gotten back to me and I guess they're talking to LTwoo... i sent them a strava ride i did where the temps were around 32 degrees where the button got stuck and another ride a few days later where it was 55 degrees and the button was fine again. Waiting to hear back...

I wonder if moisture is getting trapped in your shifter assembly, which then freezes in the cold temps causing the shifters to get stuck? I do a lot of climbing and descending, so I'm constantly shifting throughout the gear range. At least in the 40 degree + range, it's not an issue. Maybe you can coat the shifter spring assemble with some sort of anti-moisture lubricant?

I doubt it's moisture and actual ice... the buttons were still clicking this last round. It just thought the big paddle was constantly being pressed. I think some thing is contracting at the cold temps that's not allowing the thing to return to where it needs to be? I've no idea... just gotta wait to see what 80DesignerStore and LTwoo say.

Wondering if they've updated stuff since Jesse Coyle ran them a while ago for Panda Podium to have enough confidence to put them on their site

I feel that rear derailleurs have largely stopped randomly dying, so I think that they've done incremental improvements all along, not just because it's a new version. I'm pretty sure the first gen I installed is different from the first gen people were getting 6 or 12 months later.
Fwiw, I'm building a bike for a friend, he went for the er9, knowing that it might just die, so we'll probably buy him a spare RD and count that insurance policy in the build cost.

So far all my ER9 RDs are still working, even the one I thought died, but came back to life. That little bit of dielectric grease helps a lot for weather proofing. My EGR has been working great and the updated ERX has all the minor improvements especially the new brake calipers.

The only thing I don't like about the LTwoo groupset is the FD. Shifting is okay, but compared to my previous Ultegra/GRX mechanical FDs, it's nowhere as good. Also I wish the LTwoo FD had a skid plate, my FDs are looking worn out. I read Wheeltop users were able to fit a Shimano skid plate onto the EDS TX FD, but not sure it's possible with LTwoo.

I've actually been pretty impressed with the front derailleur shifting of my er9. Wonder though if it's to do with the shimano chainrings on the GRX cranks?

The ER9 FD shifting does the job, but I still feel the Shimano FD to be superior in terms of durability and adjustability. I have to put more effort to make sure the FD is set right and I still use a chain catcher. My Shimano Ultegra/GRX FDs were so good, no chain catcher was ever necessary. I do lots of climbing and descents on bumpy terrain, so it's something I'm mindful about. I also found switching to Ultegra jockey wheels and using the Shimano upper/lower pulley wheel orientation to help as well. LTwoo ER9 upper/lower pulley wheels are reversed and I found the chain is more apt to going off-track if you over shift.

I'm really excited for the TT brake and shifters LTWOO had on display at the Shanghai bike show. Maybe I'll be able to build an electric shifting tri bike under 8k aud

i thought i seen a build insta post somewhere with this TT groupset,cant find it now typically
