Road Bike Frames, Wheels & Components / Re: LTWOO ER9 & ERX - Electronic groepsets
« on: July 02, 2024, 10:19:11 AM »well, usually battery status uses the voltage of the battery, if the voltage after charging is higher than the normal parameters it may show you 100 % for a longer time, 0.1 Volts above can make a difference.
wich battery to chose? as Ltwoo is not effentient when changing gears, so current which is drawn by the system can overreach some of the battery parameters.
High C-Rate batteries are the ones you are looking for, as they keep the voltage stable and higher for a longer time if.
Usually good e-vape cells should do the trick..
Sometimes it is also necessary to check voltage directly after completed charging cycles, i have seen some major offsets regarding charged batteries, which basically indicates a bad charger hard- or software, but i do not want to complain again..
I don't know anything about batteries. Vapcell was a brand recommended on /r/flashlight on Reddit. I just went with something that seemed to be a good price and brand.

I'm using these batteries and no issues with it for the past 7 months.

So I had an issue with the charging cable not charging properly. Plug it in, app shows it's charging but after a few hours battery percentage remained the same. I realized I needed to plug it in and the USB light on the usb plug side had to turn red to charge. Something was stuck inside the charging attachment part and I couldn't get it to charge properly. At least it works now, but only in certain angles.

I just added it as Di2/Electronic Shifting and it showed up.

You got the one that's for the Magene Radar tail light, it's literally 90 degrees off from the Varia, super frustrating since i had both for a while (switched to Magene for USB-C everything now)

« on: February 22, 2024, 11:23:14 PM »I too bought aftermarket batteries because I purchased the groupset without them. I am now at roughly 9000 shifts according to the app (although I'm not sure if this has been reset somewhere along the way when doing firmware updates). I've clocked around 1700km on this groupset and I've just charged it for the second time like 100km ago. So I think it's roughly on par with Sram AXS groups when it comes to batter life.
What is slightly annoying is that while the battery level is correctly displayed in the app, I still get a low battery level warning every time the groupset connects to my Wahoo when starting a ride. It's a bug that apparently still hasn't been fixed. Unless one of you guys knows something I don't?
I've got the same issue on my Garmin. Shows up as low battery but the battery indicator is correct when I put it on my screen. What size battery did you get? I find I can only get about 300-400km before needing to recharge, I have 2x1000mah 14500 batteries in mine.

« on: February 22, 2024, 11:38:50 AM »It happens to the best of us! I now carry the USB charger cable with a USB C to A converter, so I can quickly top up just enough to get me home/anywhere to stop and charge using only my phone. Both the cable and USB converter are so compact I can easily shove them in my saddle bag.
This is genius. I went out without charging the groupset after a few months off the bike, and it was fine for the first 40km until the cafe, close to the cafe the FD and RD were getting slow on shifting (FD wouldnt shift the whole way, RD would take 2-3 presses to react), I set the gears to a manageable gear and then everything died on the way back. Would've saved me if I did this.
I did see that I had 4% battery life left before I left so it was my fault.

« on: February 11, 2024, 11:33:46 PM »So I finally got the matching bleeding kit and got around to bleeding the brakes. Rear brake went completely smooth - was done in 5 minutes or so.
Front brake however - it seems like the brifter is leaking air somewhere, when I pull on a brake lever, there's a sloshing noise, similar to sound you get when you are pushing in a water bottle. The sound is coming from the top of brifter, both the oil and air screws are fully tightened. Any ideas what could be the issue? Don't have a video at the moment, apologies.
Oh, I mine had this issue too. I needed to replace the olive (where you connect the hydraulic hose to the shifter) and that fixed the problem. Hopefully you can figure it out soon.

« on: December 29, 2023, 02:43:46 PM »These SCVCN photochromic glasses are simultaneously great and terrible.
I wore them a handful of times and they quickly became my favorite glasses, but they can't survive a 5 ish foot drop onto carpet.Arm snapped right off.
Tbh considering I paid $2, I'll probably buy them again.
Similarily, I like the POAT photochromic glasses (pretty sure it's a POC clone). The ones with the multicolour sides are built better than the solid colour sides (they use a different plastic for the solid black or white glasses arms and it feels much cheaper). One bad thing is the lens pop out once in a while, but you can just pop them back in no problem.
I have 4 pairs that I cycle throughout the year, and no issues with them. They've survived falling off my helmet quite a few times too, everytime the lens just pops out and once you pop it back in it is good ads new.
I've been meaning to try the SCVCN but I bought too many of the POAT ones...

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
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.
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.
Found this comparison from 3 months ago "Does L-Twoo eRX really outperform Di2 Dura Ace? Battle of Budget vs premium electronic shifting" by
Klein Concept on youtube (see I am not allowed to use the direct url so you will have to search for it)
Super super off topic, does anyone know why I can't see embedded youtube links? It's just a blank square.

Actually now that I think about it, mounting it on a quarter mount means you have to angle your holder down and your computer away from you.
This is more of a product to be seen and not to see. I think this is the rockbros version of the Raveman FR160

What kind of brake pads besides the LTWOO pads can be used, is it the Shimano L05A? My first bike using disc brakes.

« on: November 16, 2023, 09:58:02 AM »I'm curious, looking at your frame I'd presume it'd be a sub 8kg bike maybe sub 7.5kg. Even with power meter pedals, I would think going with ERX would offset a bit of the weight. The 105 R7000 isn't that heavy either. Is it your 60mm deep dish Elite Wheels and/or cassette that's adding weight?
I think even the real pinarello is a pretty weighty bike. I definitely didn't go the weight weenie route, the 60mm Elitewheels SLT were about 1750g, cassette is a Shimano Ultegra 11-32. I'm using a cheap set of IIIpro disc brakes, not sure if they're lighter than normal disc brakes. Also, ERX groupset is quite heavy compared to a mechanical groupset too.
Quick question about the saddle bolts, how do you tighten a saddle without a cutout in the middle? I realized that one of the bolt faces upwards, and if there's no cut out in the saddle, I have no idea how to tighten it.
