I'm okay with the low durability. It's the subpar shifting experience I can't live with. All is not lost though. I have another Chinese cassette called jfoyh or something weird like that and it's as good as Ultegra 8000 just a little lighter. I didn't see that brand making mtb style big cassettes though. May be I should look deeper. On even cheaper side than Sunshine, there's Think Rider whose cassettes are about $17 for 11-46. I might give it a try.

Thinkrider cassette I had that came with the Thinkrider trainer was bad. There was one gear that I had difficulty in getting into.
Sunshine I was ok with it.
Now I am waiting to test my SRoad one when the weather gets warmer.

The first set I have probably around 9K km on it and the second set around 2K km.

I had the option to choose Novatec or Powerway Hubs and Ih heard more people perfer the Powerway Hubs over navatrc for reliability. Powerway Hubs are also lighter too. Getting spare freehubs was not a problem, picked one up for around $35. Bearings can also easily be ordered through bearing suppliers.

Why not order from AliExpress? They have a store there. You might have more option to customize colour, finish, etc. Through their Ali store. If you are going with Powerway R13 hubs, see if you can request for the 6 paw over 3 paw free body. Sounds a lot better too.

Not Ali-ex but anyone going the weight-weenie route, I don't think there is any lighter cassette than this? The 11s cassette weighs just 118 grams. My ultralight 1 piece Sunshine cassette from Ali-ex weighs exactly 225 grams which I thought was pretty light compared to equivalent Shimano one but this is straight 100 grams saving over that. Sounds crazy.
I had not heard of this website or brand before but they seem to have some pretty unique bits and pieces for sale:

The Campy cassette is on clearance at $90. Not cheap but its weight weenie stuff to core.

Why not the SRoad cassette 11s 11-28T, my one measured to be 185g. At least it is not 100% aluminum. The only downside was the lockring that my one came with was more like cheese (aluminum)...

LTWoo's latest Promo video on their hydraulic groupset is on Youtube now. I can't seem to post the link?

Looks like they have changed the shifter ergonomics!

I have the xcadey Power-S spider power meter with the zrace RX crank combo since the beginning of the year. Seems to be working ok for me and had a few firmware update along the way. Power numbers seems about right when looking the at  numbers compared to the trainer.

Installation was straight forward minus the bolt pattern offset doesn’t seem right, couldn't get the pin on the chanring to be behind the crank arm. Also the offset of the spider vs. The zrace spider is off by 1mm so needed to adjust the front derailleur

But I could recommend using Xcadey from my experience (sample size of 1)

Or can you ask the hub supplier for a technical drawing of the hub? Normally hub suppliers will provide that info and we can see the bearings for it

I have got my hands on this groupset including a nice looking L-TWOO branded crankset, everything seems really decent quality. Unfortunately there is a small cut on one of the shifter hoods that I suspect was caused by the shift cable abrading it in transit.

That looks like a zrace Rx crank. Do you know if the shifters still click once it reaches the end of the index or does it stop?
