Title: chinese 11 speed 50t cassette
Post by: gf on May 15, 2025, 05:15:51 AM

Hello, currently on my gravel I have 1x11 configuration with 38t chainring and a Sunrace 11/46 cassette, Shimnao grx shifter, Ltwoo gr9 rear derailleur.
Now I am considerng to replace with 40t chainring and 11/50 cassette, in order to gain something with smallest and biggest pinions.
Has someone experiece with 50t chinese cassette? I have seen on aliexpress some models from Sunshine or Goldix, calimed around 380 gr (about 100 gr less than my current Sunrace), that cost around 80/90 euro.
Are these cassette reliable? There are other option in the same price range with similar weight?
Thanks

I have a bunch of the ZTTO 11-50 cassettes. Never had any issues with them over 1000's of miles

How long do you think these cassettes will last?

The ZTTO cassettes are generally decent, but the only weak point is the alloy big cog. I've broken cog teeth from rough shifts. I find Sunrace has stronger alloy material which generally last longer if you're on the granny gear often. Though the Sunrace black cassettes look like crap after a few rides. They seem to be painted unlike the anodized steel of ZTTO cassettes, which tend to look nicer after regular use.
