There were definitely some teething issues with this eRX groupset from L-TWOO when first released, but how is performing 6 months down the line?
AliExpress store where I bought my eRX groupset:
https://s.click.aliexpress.com/e/_DnM6ach
The eRX from L-TWOO was the first electronic road bike groupset to come from a Chinese manufacturer. At around £600, it comes in WAY cheaper than competitor offerings from the likes of Shimano, SRAM, and Campagnolo, but the first few units had some issues.
The battery holders caused groupsets to fail suddenly, there were allegedly some waterproofing issues, and on my groupset the front derailleur died suddenly for no reason. However since highlighting these early issues, L-TWOO have been working on improvements, and since getting some replacement parts, my eRX groupset has been working flawlessly for the last 2000km.
The ergonomics are great, the braking is absolutely fantastic, the shifting is quick and reliable, and the battery life is very impressive.
To start with, I was very hesitant to recommend this groupset. The issues were unpredictable, there were random differences between groupsets, and ultimately £600 is a lot of money to spend on a groupset that may fail mid-ride. But with the work L-TWOO have put into improving their product over the last year, I feel it is at a point where it has become a viable option for new bike builds.
Big thanks to @ChinaCycling and @GCPerformance18
