Decided to make a thread for the ltwoo rx groupsets. I expect a lot of ? will be asked about what parts can be mixed and matched.

The new rx has reach adjustment that adjusts with a 2mm hex screw on the front of the brake.  There is a rubber tab on the inside of the brake levers. It stops the shift lever from clattering but the lever does hang up on the rubber every so often.  This leaves the lever about 2-3mm unflush with the brake lever this has not impact on performance. I'm use to some texture on the shifter levers.  The levers are very smooth other than the screen printed logo under the clear coat. Reminds me of campy.

The thumb shifter does take a firm push. I think it will be usable from the drops. The rubber hoods feel nice and thick. Can see the mold seam which won't be felt I'm just surprised to see it with how nice the shifters look.

Brakes have to use their adapters. there are 4 to choose from 140/160 and 160/180.  Tons of bolts. Compression bolt,olive and barb given.

My general feeling to the groupset is there are some very nicely done parts but I notice when there are corners cuts.

The front derailleur has cable guides. The front has a built in cable adjuster. Front cage is stamped steel. Rear looks nice has a nicely done carbon front cage and metal rear. There are two type of pulleys with the lower one having a more wave design. Both derailleur still use cheaper materials and manufacturing.   The spring is small on the rear derailleur compared to shimano 105 5800 and sensah SRX. It's not as hard to move as the 105 or SRX but the tension seems fine.

Haven't played with anything on a bike yet. I hope it does what I have planned.

Weights
Shifters 582g
Brakes with hoses and adapters 372g
Rear derailleur  218g
Front derailleur 108g

Just got the RideNow TPU inner tubes and a patch kit. They are light and very thin.  They have 65mm plastic stem.  Most debate has been over tpu use on rim brake wheels.  RideNow user manual refers to minimum tire size,thermal warnings, and safe use for rim brakes. 
The manual suggests to lower tire pressure as air and tarmac temps get high from morning to afternoon. They also ask that you lower pressure 20psi before long descents. They also ask you to take breaks on decents.

I bought them for my disc brake wheels so not really concerned. I also will be using as a spare on my road rides even for my rim wheels. There is so much saving you could be extra cautious and take 2 ridenow spares and still be half the storage needed as a latex or butyl tube.

My latex 156g + butyl spare 100=256g
RideNow  3x34g = 102g
Saving 154g

I'm watching for issues that have scared me away from TPUs in the past.  Hard to find leaks. Hard to patch or patch later failing.  Leaking around valve.  I'm being extra careful attaching the pump to the valve. I don't want the plastic stem to stretch and oval out.
