Re: LTWOO RX hydro sets If you bought it from AliEx, I'd contact the store you bought the groupset from and see if they can send you replacement shifters. If not, try contacting Ltwoo directly and see if they'll replace it for you.

Has anyone ever needed repair parts for this Ltwoo groupset? I couldn't find it anywhere to buy it.
I ask because I have the R9 and the UP button broke, for no apparent reason, it never fell down.


Store I bought from (80 Designer store) sent me a replacement GR9 shifter after I couldn't get it to shift right and I just had to pay shipping.
Contact the vendor and see if they can help you. If you're stateside, I have a spare right shifter I can probably get that paddle to you if you cover shipping.

Thanks for the guidance. Despite having purchased the groupset more than 3 months ago on Aliexpress, the seller will send me a new one as this replacement part does not yet exist, not even Ltwoo Official has it.

Glad they're helping you out. Any idea what caused the break? Seems like a strange location for it to fail.

Re: LTWOO RX hydro sets I think it's been mentioned on this forum that LTwoo used riveted ABS plastic for the left and right shift levers. Constant applied pressure makes it susceptible to breaking. I wouldn't even bother with LTwoo mechanical levers. You'd be better off using Sensah Team Pro 11 or 12 speed shifters with LTwoo derailleurs. In fact I just built a bike with this exact same configuration (Sensah shifters, LTwoo front/rear derailleurs).

Edit:
Actually looking at photos of the gr9 a bit more closely, I'm wondering if there's an two versions?
I've got the first one with no cylindrical part. The second one has it, which looks a lot like some form of clutch/damping.


Correct. The first was the purely mechanical version. The one with the cylindrical tensioner was when they went hydraulic. Looking at pics on Ali, there might even be a newer version GR9 with a more streamlined looking rear mech.
