What is unacceptable is that Ltwoo just stopped making and offering repair parts for a groupset after 1 year. How anyone would continue to buy their products after doing that is beyond me. I won't purchase from them again knowing that if a part fails then I'm SOL because they couldn't care less about our market.
eRX parts are interchangeable. eRG is supposed to have longer shifters, so not compatible. BTW, EeRX shifters are also unavailable! Possible they eventually release more stock, but if not, Ltwoo needs to be widely denounced on forums like this so others don't fall into the same trap. It's a simple public service announcement (fool me once, shame on you, fool me twice, shame on me).

This is exactly the issue with this manufacturer- not much confidence in them as stated following Trace Velo videos and he keeps pushing them even though he has had issues with every iteration they sent him.
As a customer you are left swinging in the breeze if anything(and lets be honest- if more than likely will) goes wrong.
nobody can afford to take a 500-600e punt and hope for the best!

whats Ltwoos warranty like?
seems like they are busy.
trace velo has gotten every iteration and had issues with each of them.
I dont know anyone who can afford to trial groupsets each time.
once bitten twice shy imho

no luck with original ridenows white valve on gravel but ok on road.
find if you hav them installed on a tyre and go to change same tyre ,slightly inflate as normal but can rarely if ever get them to behave on install as tey would originally.
could start my own tpu factory here! - so many punctured hanging on wall!

Can anyone share on how to repair a punctured tpu
I have two ridenow patch kits with hobson rubber cement ??

thinkrider out of the pack wont hold air  - absolute shite.

off bondage  purple black threaded long vale with valve wheel holder.Bought three
2 punctured/lost air very easily on install - i did take extra care but no difference wouldn't hold air - factory defect .
were 4.89 each now 8 e each - junk.

i need a viable alternative.
cyclami seem to be good.
Gustavo ?

help me obi won!

take off both outer screws
inner screw pushes guard in or outboard by extending thread out/in.
eyeball it and lock in gap on middle screw,then reassemble outer 2 screws leaving the desired gap.
i have this on my 1x TT setup 56T oval chainring so err on side of caution with bouncy chains out west of ireland.
Crap roads!

darevie jerseys and RION bibs for me
great quality V price!
Sizing bang on
Inbike bibs run small
Ykywbike bibs chamois is too far forward by about 20-30mm so less padding where it's need on ass.

sold mine
went for bryton 650 for 134€
had 750 previously and liked their editability on the go.
used to their ecosystem

s810 is brytons flagship unit- not comparable at all tbh imho
i was looking at 650 as a direct replacement for gravel navigation- need it up the hills!

looking at this unit or
bryton rider 650 or
magene c606 v2.

what should i go for ??
primarily for gravel navigation
climb pro challenge and segments a  - nice to have.
not essential

update
IGPSport BSC500 on the way very soon
