LTWOO ER9 & ERX - Electronic groepsets

[PLA]

My local Shimano dealer here in the US is having a sale on 105 Di2 12sp groupsets for around $1000 usd. Not as a cheap as ER9/ERX, but in less than a year's time I would have forgotten about the extra $500 in exchange for running a proven and reliable groupset.

Yes.

Been lurking on this thread for a minute. Thanks for sharing the 80s designer store! The 1035 code doesnt work in USA but i found another code that did $30 off on top of the $10 that was already off. Came out to $450... Cant wait for it to get here and i'll post up about my experience with it when it does!

Is there any way just to get the 105 Di2 shifters, calipers and the FD/RD derailleur only? You can cut weight going with an Ultegra cassette/crankset or go with an aftermarket setup.

Yep. I just picked the shit I wanted and bought them from all random places.

Merlin, Amazon, some other random joints. Worked out way cheaper to get separates. Was planning to mix/match shimano and ltwoo but it turns out ltwoo is utter garbage. Ended up with

105 fd/rd/crankset. Good cash savings, similar performance and weight. 105 rd has same internals as DA/ultegra. Have more faith in 105 cranks vs ultegra.

Ultegra shifters and cassette. Wanted top buttons n satellites without faffing with wires to a battery) and cassette has good weight savings for the cost. Servo wave is nice vs my 105 that doesn't have it, too, but whatever.

GRX brakes (same as 105/ultegra)

DA rotors (look coolest and same price)

Made my own satellite shifters for tops n drops for like 30bucks

This website provides 105 di2 parts in OEM packages:

https://www.bike-components.de/en/s/?keywords=105+di2+OEM

RD/FD+shifters+crankset for 595€ [you still need the battery and the cables though which adds 240€].

They had an offer where the complete Groupset was only 769€. I should have jumped on it.

I think you are missing 1 shifter for that price...

190+190+132+67 = about 580 € for shifters, brakes an FD end RD without crank

What 11 speed 11-32t cassette would you recommend with ER9? Nothing crazy like DA/Red, I was thinking about trying SLR2 sold by Lexon store or Sunshine

[chughes]

@kubackjeee yes I would consider buying it 1. It allows me not to have to upgrade from 11 speed right away 2. I reside in the Caribbean on an island named Antigua and unlike Shimano's etube software, I would not be geo-blocked. This means no need for me to have to use software to hide my ip. 3, Its cheaper than the alternatives  4. Really see no red card but more a yellow one and recently heard of a Shimano recall that were I to have one of their cranks, I would still be at a loss due to my location.

No because my VAT is at 7.7% so

167*2+59+118+85=596€.

I would just get an Ultegra 11-32t cassette. I'm not confident with the SRoad/Spedao cassette I'm using. I bought two cassettes, the first one skipped big time on the 12t cog, so I returned it. I'm on my second cassette which is a bit better, but I'm not sure long term if the small cogs can handle the torque when going out of saddle. Normally I'm not mashing on the 12/11t cogs, but sometimes on hard sprint climbs, I do drop into high gear while on the small chainring and there might be too much torque for the cassette to handle.

I'll probably swap it out with an Ultegra cassette if it goes out.

You guys are really buying this stuff even when youtubers known for loving Chinese stuff gave it a red card?

Well, they are only youtubers....they seems to forget how hard sram failed when starting with their electronic groupsets..i remember a race, where 5 people were sitting at the side of the road not being able to change gears with their sram, sebastian kienle had failures on racing hawaii with sram..
So, why not give LTWOO the time to get stuff done...
We are currently planning to sell these units, even with aliexpress selling it lower than we buy directly, but customers are in the market for budget custom gravel builds....and it is great for the market....we need to show shimano, that their pricing needs to be adjusted.
the low prices on the shimano di2 sets are made by the dealer ships, shimano has still their high price attitude and in europe, margins are not there....a normal bike shop buys shimano stuff cheaper online at some outlets, than referring to the official distributor...

That explains a lot

Has anyone figured out yet what the “gear protection” and “one touch shift” options in the LTWOO companion app actually do? They don’t seem to make a difference when I shift.

Also, does anyone else also have the bug that the app shows the battery as always fully charged? I already received two firmware updates but that issue persists.

"one-touch" seems to cycle with a single button.

So for front deirauller, it just goes 1-2-1-2-1-2-1-2 regardless of the button pressed.

Fucked up my entire setup at first, lol.

Wish shimano has a toggle function for fd to free up a button. Annoying.
