Ltwoo erx TT

[ProtonClimber]

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.

I've been using the Ltwoo erx TT groupset for about 4 months now with no problems. I bought it because it was cheap and i just wanted to try it. I do local club TTs, its not like i will pay big money to fly somewhere to do a race, and i'm not in the league to compete for a national TT title, so its a low consequence should it fail on me on race day. Agree with what others have said above - if you want a more reliable option go for SRAM blips with derailleurs, and pick a non-shimano/SRAM hydro brake setup.

I would say the TT groups would behave similarly to their respective road counterparts. Lots of issues with ERX road (ERX-TT looks like it would be equivalent to the ERX V3 but who knows with all the different SKUS and random updates they do). Some users have no issues, others are plagued. It seems like part replacement/availability is not there and a huge lack of warranty/customer service. Seems like very few places even list it and the prices vary a lot like 750-1200USD on aliexpress.

Wheeltop is probably in the same boat, I've seen a couple reviews and they have a weird delay when shifting from the brake levers due to the single button waiting on double presses for FD shift. The 2-3 youtube reviews are positive but I think they got them sent for review and probably don't show any hassle setting it up.

It is not cheap enough to justify it over something like sram rival/force with blips which are completely wireless and WORK and either riderever trivia or mechanical brakes (or mechanically actuated hyrdos). There are tons of sales on rival/force D2 and the used market is pretty good. Both of the chinese groups are disc only which removes them from being an option for someone picking up a cheap used rim brake frame.

LTwoo ERX V3 hardware is fine if you have a brain and can actually figure things out. If not, just stick to Shimano or SRAM and pay a bike shop to handle it.

I was going to build my upcoming TT build with Ltwoo since i used the ERX v3 on my roadbike this summer with no issues at all. Loved the groupset!
But now when i did not use the bike for about 4-5 weeks due to sickness and took it inside to my trainer to set it up for the winter the app has lost the groupset and I can not find a way to reconnect it.
And Ltwoo is not answereing emails, so now i am not able to use it after a reset and the shifting only works on about half of the cassette.

So before i find a solution to my problem i can not recommend it.
