At this point, I'd just wait for the upcoming full wireless 13 speed eGR groupset to drop. I don't like the idea of having to unplug the battery cable and use a proprietary usb cable to charge it.
Yeah i wish i had waited a bit more but i ordered my set around a week before new full wireless got announced. I could just refuse my package, but seeing that we do not know when it will go for sale, what price it will be etc. I decided to just stay with old design. But as I stated in my other comment, while i think that 13 speed and full wireless is nice I do see some drawbacks from new design as well.
Let's start from the positives:
- 13-speed, obviously it's great having an option to go up to 13 gears, but atm 13 speed cassettes are quite expensive and there is also a weight drawback, so while nice options ot have imo its not really essential.
- Full wireless is great, no flimsy cables or battery pack, but it has drawbacks i will discuss later.
- Seemingly much more robust B screw bracket and metal piece(yes the one that snapped in blue version for trace velo).
- RD of the same weight even when it has battery attached now(overall system around 80-100g lighter)
- USB-C charging, no flimsy proprietary charging cable.
- Possibly cheaper due to less components(no left shifter buttons, no cables or battery pack)
For drawbacks
- First generation of full wireless, might have some hidden troubles that did not get caught by Ltwoo, like many of their other first gens.
- 400mAh battery capacity. Previously we had around 1600mAh in the seatpost pack that Ltwoo claimed lasted 3000km, but many user claimed less. Still had an option of putting vapcell F15 in there for example and get total of 3000mAh capacity(7,5 times what full wireless has).
- No shifter buttons on left lever
- No swappable battery
I think overall its a step in a good direction, but at the same time at one point i was thinking I could try to use er9 FD. No Idea if it will work yet, as there is not a lot of information but it would be pretty cool if it's a viable option. I would need new battery pack and cable but i could have USB-C charging and an option to go 2x. And replacement cables are still like 20$ so I think i'm going to order them just in case they become unavailable later down the line. But still my main reason is battery capacity and possibility of maybe creating 2x system as i live in pretty flat place. The only reason i did not go for eRX is becouse I still enjoy riding forest or dirt roads the most.
Overall, I wish i knew they will refresh eGR a week after i ordered, but at the same time I don't think it would change my decision.
