All Third-Party Brands Road Electronic Disc Small Groupset Weight and Other Info

[VonPG]

These are All Third-Party Brands Road Electronic Disc Small Groupset Weight and Other Information.
1* Measured by Gravel Cyclist.
2* Measured by Josh Ross.
3* No 1x Support means you cannot remove Front Derailleur when you use single chainring. But you can still use 1x chainring after Front Derailleur installation.
4* TM to TM = terminal male to terminal male. If you don't want to buy original wire, you have to bespoke these wire from some headphone experts because there is no MMCX TM to TM wire at present.
5* So far, their reliability are not so good when compared to Shimano/Sram. If you just want to try something different or have very limited budget you can buy it.
6* Only list MSRP in China.

Very nice, thank you. Is there an excel version? Are the columns with Shimano 105 available? i wonder how ltwoo er9 compares with 105 vs ultegra.
The ltwoo stuff, the calipers, afaik, they're the Zrace type i think now, shaving 120g or so? i'm not saying the table is wrong, because it's incredibly confusing and ltwoo at this point doesnt want to sell to the west anyway, but technically i think whoever gets the "latest" iteration of ltwoo groupsets gets calipers that 1. look very different from what shipped originally and 2. weigh much less.
Alas, i may be confused myself, maybe its' for the gravel version or god knows what shenanigans.

I will upload later in GOOGLE DOCS.
ER9 small gruopset weighs 1321g(1x 1181g), R7170 small groupset 1216g(1x 1074g), R8170 small groupset 1123g(1x 1012g)
You can see new ltwoo caliper here:

https://www.ltwoo.com/en/productDetails?typeId=82&id=453

New caliper made in one-piece. But it still have a similar outlook comparing to old caliper. So it also has an old adapter. It is made in Ltwoo itself.
Zrace caliper is the similar version of Sensah HRD's. These two calipers(Zrace and Sensah)are all made by iiipro.
But ltwoo's brake power is better than iiipro.

Just for the ER9 the weight is quite niced up and it would do absolutly nothing, neither shifting or breaking.
I weighed my when it came and i ended up on 1414g with uncut hoses and all batteries and srews and adapters for the brakes. So roughly 8% extra.
