GOLDIX Compatible 11-12 Speed Cassette, All-Steel Ultra Lightweight Bicycle Flywheel for Shimano Road Bike / Gravel Bike

I bought this steel cassette 2x11 from AliExpress and it lasted around 1500 km before it started skipping on the third cog. I took very good care of it and cleaned it almost after every long training ride. To be fair, I had no issues with shifting performance at all, and personally the slightly louder noise compared to Shimano didn't bother me. But honestly, I wouldn't recommend wasting your money on it. And this is coming from a rider averaging around 190W during training rides, so I can only imagine how long it would last for stronger riders putting down bigger power.

I have 4,500km on my Goldix 12 speed 11-34 and it is faultless so far.

Goldix 11sp 11-34 steel cassette: 191 grams, as advertised. Swapped with Ultegra CS-HG800, no adjustments, shifts very good (Di2), maybe a little bit biased towards shifts into a harder gear. Have not bothered to adjust the 1-2 clicks yet. Going to swap another bike with mechanical shifting soon.

That’s the one I’ve been posting about. -It’s louder than DA. -Shifting is acceptable. -You need to bring the RD as close as possible to the cassette by adjusting the B-screw. -The price and weight are very good -No idea about durability. Time will tell. You can add SRAM Stealth Rings to improve the noise as the monoblock design is considerably louder than Dura ace cassettes. If you want the best shift quality with those ratios and don't care about weight, you can get the Shimano 105 11-36 (380g). That cassette is cheaper than most lightweight aftermarket cassettes. Alternatively, you can make a hybrid cassette with a DA 11-34 and a 105 11-36. Use the largest 3 cogs from the 105 and the rest from the DA - that results in a cassette with those ratios but saves 25g. I've only used it on waxed 12 speed Dura Ace chains. I purchased it from this store: New Bike Store. Nothing out of the ordinary for this order - it arrived in approximately 2 weeks to Switzerland. I've since gone back to the 11-34 DA cassette since I don't need that extra range of the 11-36. There is a night and day difference in terms of shift quality and noise.
