So, after roughly 40.000 shifts of flawless performance, my groupset is finally showing issues: I'm experiencing battery drain. I came home from a vacation trip and the bike was stored on the wall for a week. The RD was dead because the battery was fully drained. I recharged it to 100%, went out on a 90min ride and it was down to 82%. After leaving the bike for another day it's now at 59%.

Has anybody with these kinds of issues found a cause and/or solution? The batteries have given me zero trouble so far. I doubt that that's what's causing the problem. I'm gonna clean the plugs and connectors and weatherproof them and see if that does anything.

I had the same thing happen to me after being caught in the rain. 80 Designer store sent me a new rear derailleur. While waiting for the new one to get in, the old one did start to hold charge a little better over time but I went and swapped out the derailleurs anyways and everything was running good. No idea how the old one is doing now as its been sitting in a box since all this went down

Woohoo! 80 Design Store replied back and they are sending me a replacement ER9 rear derailleur! It's definitely worth paying a little extra to get customer support from them on products. They've definitely earned my future business.

Hell yeah... I definitely check their store when Im looking for stuff nowadays before going anywhere else!

Well I caved in and pulled the trigger. I usually won’t buy something that doesn’t have at least a few reviews, but I guess I’m the guinea pig for this one. Came out to $238.63 after coupons and taxes.

Looking forward to hearing your experience... winter is coming and this Californian who now lives in the east coast is too soft for winter outside... haha

FYI - Looks like you're running 140mm disc in the rear? If you are, be careful with tightening the caliper bolts. The alloy screw holes is very soft on the ZRace XG calipers and can possibly strip.

Good to know... thanks for the headsup!

So I went and impulse bought some Zrace XG calipers for my Ltwoo ER9 groupset. Was wondering since the pistons are both 22mm but the Ltwoo ones are ceramic and Zrace is aluminum... has anyone here swapped them to see if they're interchangeable? Lol

Got the Zrace calipers in and put them on. I think this is like a 3rd gen? Unlike Tracevelo who has two separate ports where the hose goes into and Fiveminutevelo where the there is one main port and one half port for the second piston... Mine only has one port so they've machined it differently and now the fluid gets distributed to both pistons after the ONE port from the hose. Pistons are still the same black alloy ones. I haven't had a chance to bed in the pads and ride them yet so we'll see but initial impressions is that they are feel better than the stock Ltwoo calipers with the lever feel. Overall looks to be pretty well made and really looking forward to giving this a go!

It's pretty much stuck now at the lowest gear. It just won't shift. I might tinker with it some more to see if I can get it to wake up, but it just makes a click sound, but nothing is happening.

The 80 Design Store messaged me. Unfortunately (for me), it's National Day in China and it's a week long holiday starting Oct 1st. They'll get back to me next week. As long as I can get a warranty replacement, I'll be fine.

Could it be the shifter button getting stuck? Like I had an issue where the spring wasn't strong enough to push the buttons back out. It was like two Phillips screws, take the buttons out, stretch out the springs and put them back together and my problems were solved

There's no way to switch which button is up and which is down on a given side, right? When sprinting I'm struggling to hit the rear button on the right to get a harder gear.

AFAIK there isnt except for the front derailleur where you cans wap it to be a single button shift

In the market for a trainer as winter is coming and saw these cheap on Aliexpress... Anyone have any experience with these? I've used Kickrs in the past. How do these compare? Thanks!

I have them on my bike but haven't tested or driven it yet. However, 1 of them was true /straight and the other one came in wobbly. I think it's maybe the packing and handling from the delivery service. Not sure if this is common but yeah if they don't work I buy others that are already proven, like the comments here. Mana, Onirii or Galfer. The Galfer will be lighter too.

Hot dang!!! Didn't realize Galfer made light weight road bike rotors. Those claimed weights are amazing! Any real world weights out there?

That could be a cheap solution if they use the same size piston. Have you measured the zrace ones?
If its a tolerance issue with zrace, then they probably won't solve the problem. I just ordered some grx400 calipers for $33 from ali to replace my ltwoo calipers. Couldn't resist at that price.

Trace Velo measured and said they were both 22mm? But i'm not sure...  I'm probably going to run the stock ones for a bit when mine get here and then if i'm not happy with them do the swap. I also noticed Lewis uses Ti pistons which is interesting! Never seen that before

Anyone here run these before? I'd save quite a bit of weight even with running centerlock adapters... Wondering about durability and performance. Thanks!

I switched back to GRX calipers mainly because I found the XG pistons tend to be sticky after long descents. They could be better if they were fitted with ceramic pistons.

Good to know... yea the zrace were an impulse buy as they were like $55 shipped for a pair... Sounds like possibly the aluminum zrace pistons expanding under high heat? I might try and retrofit the ltwoo pistons in there and see if that works if i dont like them haha|

Or maybe i could try something like this

Hi, how was the response time from 80 Designer Shop. I have raised an issue with a dead EGR, they quickly replied with standard checklist to check and then silence and no answers in a couple of days. Did you also experience long response time.
Thanks,
Christian

response time was pretty quick... I got the standard checklist too but told them I went through all of that already and told them it started happening after some crazy rain. They got back to me in hours saying they'll contact Ltwoo. In about a week they sent me a new custom order for $15 for shipping and in two days, my new derailleur was shipped
