AI-Summary
Pros
- Incredibly cool look with super vibrant anodized colors
- Very lightweight (117g for the 11-28T 11-speed model)
- Significantly cheaper than when this type of cassette first came out (cost them £61)
Cons
- Durability is a trade-off, especially for riders in hilly areas who use the aluminum climbing gears a lot (may only get 1500 miles)
- Shifting quality is not quite as smooth as an official Shimano Hyperglide cassette
- Can be a little bit noisier
Key Points
- Construction: Higher gears are milled from one block of chromoly steel, climbing gears are aluminum to save weight

- Price: Cost the reviewer £61
The 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.
