Are cheap cassettes durable enough? AliExpress vs Shimano
The reviewer discusses the ZTTO SLR Gen3 11speed Road Bike Cassette as a replacement for their worn-out monoblock steel cassette. They mention it is incredibly lightweight at just 122g and is the latest generation from ZTTO, referred to as the SLR Gen3. However, they express concerns about its durability, particularly due to the aluminum teeth on the first three sets, which they expect to wear out quickly. They plan to test it and provide updates on its performance.

How I Built a Sub-6kg Climbing Bike for Under Β£1000!
The reviewer discusses the ZTTO SLR Gen3 11-speed cassette as one of the most exciting upgrades made to their hill climb bike. They highlight its extremely low weight of 113g for the 11-28T version, which was a significant factor in their decision to purchase it. They note that the cassette's teeth are well-machined with proper Shimano-style ramps, resulting in brilliant shifting performance. However, they express concerns about durability since the top three sprockets are made from a single block of aluminum, suggesting it may not last long under heavy use. The reviewer clarifies that this is intended as a race-only cassette that won't see many miles, hoping it will last at least a season.

AliExpress Cassette FAIL During Brutal Hill Climb Race
The reviewer discusses their experience with a cheap AliExpress cassette (likely the ZTTO SLR Gen3 based on context) that failed during a hill climb race. They mention the cassette started skipping under power, particularly when standing on steep gradients, which ruined their race performance. After replacing it with a Shimano 105 cassette, all issues resolved immediately. The reviewer reflects that while the lightweight AliExpress cassette (approximately 112g) offered weight savings, its unreliability outweighed any benefits. They acknowledge that sometimes budget components work, but this was a clear failure case.

Cons
- Chain skipped repeatedly under power
- Made standing on steep gradients impossible
- Unreliable performance during critical moments
- Forced rider to sit and lose power
- Caused significant time loss in race
- Required immediate replacement
- Not as tested or designed as branded components
