Title: ZTTO UL 10-50 cassette performance
Post by: jefflinde on February 13, 2025, 12:17:56 PM

I am looking at the ZTTO Ultralight micro spline cassette 10-50 or 10-52.  does anyone have any experience with these cassettes.  I have had some mixed experiences with other non-micro spline cassettes as far as non-precise shifting.  I am wondering if these cassettes perform close to the actual Shimano cassettes.

Its not worth it. Did try the sram version.  Couldn't never get it to work decent. My xx1 did always work.

I own and use a 10-50 ult microspline with shimano xt and xtr gears, perfect, I will mount a 10-52 on the next frame with gx eagle gears, I will let you know if it will also perform well with the latest generation sram

Tried their 11-speed ULT PRO 9-46 (fully CNC'ed), pure trash. Shifting is unstable and cracky, super crusty noisy work. Got back to SLX. IMHO, 100 grams less is not worth potential problems, especially for the 100 bucks price + taxes. Would go for the classic shimano or sram.

evidently what you tried is different. with the 10-50 ult I save a good 300gm compared to the original deore 10-51 not to mention the price, in Italy a cassette of the same weight shimano or sram costs at least quadruple. luckily I have never had any problems with operation but I have noticed that the scaling of the ratios is the same as sram not shimano.

I have 4 of the ZTTO 385 gram Micro Spline, 12 speed, 10-50 cassettes in service, all running KMC chains and Wheeltop EDS OX derailleurs.   (I was one of the first purchasers to start using the Micro Spline version when ZTTO first introduced them.  I was told by them that the first 2 I ordered were from their first manufactured batch.)

The oldest cassette has 3000+ abusive miles on it and is still working great.
The other 2 are on bikes I ride a lot less.
The 4th is on a spare wheel.

I also have 2 Scumano M-8100 10-51, 12 speed, cassettes on wheels that I swap out on a couple of my bikes.  Amazingly, I don't have to re-adjust my Wheeltop EDS gear cog/shift positions, and I can't tell any shifting differences between the ZTTO and my Ultegra cassettes.   (Other than having a 51 versus 50 lowest cog.)
