Hi there, fellow triathletes, time trialists and lurkers!
I am slowly doing my research regarding what is needed for a future proof budget TT bike. There has been some discussion on framesets already (Ican, velobuild, Winow), but I haven't found reliable review of the L-twoo erx TT groupset in title.

Has any of you decided to build a bike with this one?
My impression is that sram is the easiest to get going, but uses dot fluid and is more expensive than shimano in the long run. On the other hand, shimano offers only 9180 levers for hydraulic disc brakes which is on rather expensive side + the initial wiring might be a hassle. But I have all of the tools as I'm using di2 on my road bike and am used to mineral fluid - tastes better.
If I'm not mistaken, the groupset uses the same derailleurs as standard non-TT version, being the upgraded v3, which has some reviews like Tracevelo.
Still I'd love to see some user feedback on that.
Cheers!

Overarching theme I hear about electronic Chinese groupsets is "not worth it, just go Western"

I used sram force derailleur with blips, brakes I used riderever triva which uses mineral oil, I guess you can go with any chinese tt brakes if sold separately

+1. given the failure rates on these products, and given that TT stuff ought to be way, way more niche and way more beta than other groupsets, racing on a chinese TT group is something i would not do. TT / triathlon --> race day --> trust your groupset.
