My LTwoo R9 alloy hydraulic groupset has arrived. I probably won't use the derailleurs and stick with Shimano, but I'll keep them around as backups. Both the brake and shift levers appear to be alloy. They feel around the same weight as Shimano hydro shifters, which is my only gripe about hydraulics. I found in the past LTwoo shifters are far easier to setup than Sensah and the campy-style shifting is fun since you can do massive shifts on gearing.
