For the last few weeks I have been testing a prototype groupset from a Chinese company called L-TWOO.

It's a 12 speed electronic gravel groupset, and in a previous episode, I found some issues with the waterproofing:

   • An OUTSTANDING groupset, when it work...  

However, once it dried out it was fully functional again, so for the last few weeks i have been using it quite a lot. It is fantastic when it works, but unfortunately I encountered another problem while on an MTB trail.

Part of the hanger snapped off, meaning the derailleur was not properly supported. L-TWOO have apparently fixed the problem, so I'll have to wait until I get my hands on the final retail version.
