The ZTTO Ultimate cassette is a lightweight, affordable option from AliExpress, praised for its unique two-piece steel/aluminum construction and vibrant colors. However, durability of the aluminum climbing gears is a significant concern, especially for hilly terrain, with shifting quality slightly less smooth than Shimano's Hyperglide.

- Shifting quality is not as smooth as an official Shimano Hyperglide cassette.1
- Can be a little noisier than standard cassettes.1

Reviews & Ratings
01:55The reviewer analyzes a super lightweight cassette from AliExpress, which is the ZTTO Ultimate model. They describe its unique two-piece construction, with the front sprockets milled from a single block of steel and the rear sprockets milled from a single block of aluminum, pinned together to save weight. They weigh it at 122g and compare it to a heavier, standard 11-34t steel cassette. They note they have used an identical gold version for about 1,000 miles, showing visible wear on the aluminum teeth but with shifting still perfect. They caution that durability is a trade-off, as the aluminum teeth will wear quickly if used frequently in hilly terrain. They mention the price has dropped since launch, and they purchased it for just over 60 pounds.
