I've said that I'm putting a 4th chain which means I'm doing around 1000 km per chain and since, it is not my only bike with 12s drivetrain, it's just being reused on one that cassette doesn't work with new chains or I don't care about shifting smoothness for ex. my enduro
KMC X12 works best for me and I'm waxin' since last year

over 3k km and since new it had some issues with shifting from 9th to 8th and 8th to 9th cog. Now I'm putting new (4th) chain and I can't seem to find any other problems with this cassette on alu sprockets nor steel ones. No racing just chill rides (around avg. 150-230W) with some harder climbs where I'm pushing from 250W avg. up to 600/800W when I need to catch a roadie and act like it's my Z2 The funny part is that I'm bearly using those last cogs just to keep them blue hahaha Honestly I just hate rear heavy gravels with MTB cassettes so this ztto in a 2x setup is doing great job for it's cost

This frame looks nice! How much are they asking without custom paint? I'd love to convince my friend to get one

tantan GR201/ Tideace Noah is anything but aero tbh but

My two big criteria are

• the frame works with 2x drivetrains. I have grx di2 11 speed in my parts bin, and running it with 46/30 or 50/34 rings and an 11-40 cassette is fantastic IMO
• it can fit 2.1 schwalbe thunder burts on a wide internal (~30mm rim) while still running 2x

Other nice to have options would be

• suspension corrected geo (or at least a ~400mm fork axle to crown)
• somewhat aero shapes
• udh
• bsa or t47bb

... all of it should be fine

If you need to know more about this frame AMA

Sooo.... 1600 km with this frame which include 2x 220 km rides
It is my main long distance bike now, but for some reason I'm thinking about going full back on XC as a ,,do it all,, since that was always my way before this project

It is a cheap brand in Japan
Had few dealers in Shizuoka prefecture

In 2023 I got my hands on SuperSix evo 2021 frame almost for free. Using local marketplace bought myself 11s 105 discbrake group, some shimano wheels and cannondale cranks. Stem, handlebar,chain,BB,casette,pedals,bartape and few other things straight from Aliexpress. It did work well and all with few ,,this,, and ,,thats,, and I was fine with this ,,cuz that price,,.
By the end of last year it came to say good bye to SuperSix and build something. Then it just became so clear that ,,What if put full chinertown style bike just for this What if part,,.
Some serch, plenty e-mails, few discounts and cupons later: Full carbon gravel that uses everything from china yet I couldnt decide for chiner groupset that was more expensive and less reliable than Shimano Di2 105.
Do I have a full support from them if anything happen? No clue but I'm fine with this. I knew I'm doing it for my ,,What if,,
Serch process was fun, building everything also. I'm glad I did it and breaking price everything was under 1900 euro which is more than 50% of known brand same spec or even lowe spec.
If you are ready that something may not go as good as you plan, just do it. I was ready for at least 50% things go bad or be just unusable yet almost all of those parts did me right from the beginning.

Had Bucklos now Ryet

I'm not sure if this has been posted yet, but it's a sub-200g HG road cassette with only a single alloy cog, the rest are steel.

I've got myself ztto SLR gen.2 just for a blue accent but recived gen.3 for same price
12s 11-34t hg 148g
perfect shifting on almost every gear beside largest steel which is bit wobbly

I think these are intended to be road wheels and not much else. I mean sure you could obviously still ride them on gravel but I'd suggest there's options better suited to that.
Serenade offer a 25internal/30external/30deep gravel wheelset that's like 1180g for around the same money or even less if you want something seriously light. Others out there have similar options, I believe.

Yeah but ngl those are visually pleasing

Size 54 im my case 

RiRo 24mm axle

Would you recon if they could work on some terrain or they are road only? This 100kg limit tells me don't but.....

Elitewheels ENT Disc are just lovely

Lookin like a white GR201 is getting popular among us
Here are few shots from first sunny day this year here.
