LTWOO ER9 & ERX - Electronic groepsets

[Dunndunn]

Can someone link the right batteries for Ltwoo Electronic? Thanks!

My 500k update on er9. I’m pleased with it. It works very well. No issues, despite a few rides in really grim weather conditions. I’ve also washed the bike quite a few times now. No problems.

I’m interested to know if someone here can compare it with other electronic groupsets. I’ve only ever ridden the last generation 11sp Ultegra Di2. But that’s quite a while ago. I wish the shifting was a bit quicker with er9, particularly when going to bigger cogs/easier gears on the cassette. The time it takes from clicking to the chain making it to the next cog sometimes feels rather slow. Especially compared to the mechanical groupsets I got on my other bikes. Also: More feedback from the shift buttons would be nice.

Other than that, no complaints.

The only direct comparison review I've seen.

Pretty much the same experience that I have. Approaching 1000 kilometers with my er9 and I wish that buttons were more tactile because I have no idea if I already shifted or not. FD shifting is not the worst but not the best either. I don't really have any comparison but my mechanical ultegra which shifts great. It is really a gateway to electronic shifting. I hope the next version of what they make would be much nicer and improved. I also tested this in rain and always clean it with wet cloth. No issues whatsoever. My 105 di2 12 speed is on the way and I would have a perspective on what will be the difference between an established brand vs a new and upcoming brand.

Already watched that. Di2 were much crispier and shifts faster than LTwoo. But he is comparing the highest tier of Shimano. He should've compared to something like Rival or 105 but I doubt there would be any difference with 105 and DA. I am happy to be corrected if someone here has an experience with both groupset

You want a 14500 Button Top battery.  Should be able to get it locally wherever you are.  I got the Vapcell H10 Button Top 1000mah 4 for $20 USD

Same with me but for the eRX.  About 400km now.  One downside is the shifters are pretty sensitive, so if you rest your fingers on it it'll suddenly shift a couple gears, it's annoying sometimes but just takes getting used to.

Super super off topic, does anyone know why I can't see embedded youtube links?  It's just a blank square.

Most likely it’s the browser you’re using. I see all links fine on mobile (safari) but not on my desktop (chrome).

Doed anyone know if the LTWOO shifters are compatible with Shimano og SRAM brake callipers? I cant get my LTWOO ER9 calliper to fit the fork on my LightCarbon frameset. Could go for the 140mm rotor, but want to see if I can get 160mm front and back. Se pictures. Other solutions are welcome

I think Shimano is compatible since they use mineral oil. SRAM however is not since they use DOT 5

I’ve paired my LTWOO brifters with Campagnolo calipers. Works great. I used the Campy pin and olive on the caliper end of the brake line. Those are virtually identical with Magura so I’m sure that Magura calipers would work as well. In fact I’ve paired Magura MT8 calipers with Campy Ekar levers on my gravel bike. And the LTWOO hydraulic units in the brifters are basically Campy copies. And I’m quite sure you could pair the levers with Shimano calipers as well.

Just for fun? Or are LTWOO callipers that bad?

It is really important to not mix components for mineral oil and DOT. The reason is : the sealing material is designed to work with the corresponding fluid. Using the "wrong" fluid leads to damage in the sealing and then leakage of the hydraulic system.

LTwoo calipers are bricks. I'd rather source some Shimano calipers if possible or use lightweight ZRace/IIIPro calipers.

I source most of my parts used. So I collected a few parts over the years.
I had a used set of Campy calipers lying around because I ended up not using them on my gravel build. They are much lighter and look a lot sleeker than the LTWOO calipers. The front one does not need any adapter for a 160mm disc for instance. And yes, I really don’t like the look of LTWOO‘s weird „postmount to flatmount“ arrangement.

I've tried this, just wanted to warn that they aren't super great IME. I'd source shimano calipers instead.
