I Broke Their Product....This is What They Had to Say
Path Less Pedaled
The reviewer discusses the SCHWALBE CLIK Valve system extensively, focusing on a failure incident where a valve core broke. They detail the cause (lateral load from a mini pump on a non-fully-seated valve), the manufacturer's response acknowledging a design flaw and material update, and their personal decision to continue using the system. They explore compatibility with various valve stems and pumps, recommend specific pump setups to avoid future issues, and highlight the system's advantages.
Pros
- Increased air flow
- Ease of use (push-on pumps/gauges)
- Minimal air loss when attaching/removing pumps or gauges
- ...and 3 more
Cons
- Valve core can break under specific pumping conditions (short hose, direct connection, many strokes)
- Does not interface well with all valve stems; may not seat fully, leading to stress on threads
- Unrealistic to expect all users to buy specific $20 Click-approved valve stems
- ...and 2 more
Key Points
- The valve broke at the threaded part where it interfaces with the valve stem.
- Breakage was due to repeated lateral loads from a mini pump, concentrating stress on the threads.
- The geometry transfers pump load to the threaded interface, especially when the core doesn't seat fully shoulder-to-shoulder.

aliexpress.comAffiliate by MyBikePartsThe reviewer analyzes the ZTTO SLR Gen 3 ultralight cassette, focusing on a specific failure case where the top two sprockets sheared off. They describe the cassette's construction: the top three sprockets are milled from a single aluminum block, with the rest being monolock steel, resulting in significant weight savings (117g vs. 260g for Shimano 105). The reviewer has personally used smaller versions (11-28T) for thousands of miles without issue but identifies a critical design flaw in larger sizes (11-30T and above). In these larger cassettes, the top two sprockets are connected to the third by a thin ring of supports, creating a potential cantilever beam effect and stress risers at sharp internal corners. This design, combined with spiky power delivery (e.g., in cyclocross) and the increased flexibility of larger sprockets, increases the risk of failure. The reviewer concludes that these cassettes prioritize minimal weight and low cost over structural safety margin and long-term durability. They advise caution, particularly for the 11-36T and 11-34T versions, and suggest stronger alternatives like ZTTO's all-steel or Gen 2 cassettes. They also note the shifting performance is decent but not as good as OEM, the cassettes are noisier, and aluminum teeth can snap if shifting under load.
Pros
- Incredibly lightweight (e.g., 117g for 11-28T vs. 260g for Shimano 105)
- Great looking and available in funky colors
- Low cost (about 60 quid)
- ...and 2 more
Cons
- Design flaw in larger sizes (11-30T, 11-32T, 11-34T, 11-36T): top two sprockets connected by thin supports, creating a weak point
- Risk of sprockets shearing off, as evidenced by a viewer's cassette failing after ~150km
- Sharp internal edges (90° corners) act as stress risers
- ...and 7 more
Key Points
- Brand: ZTTO, model referenced is SLR Gen 3
- Construction: Top three sprockets milled from single aluminum block, rest is monolock steel
- Weight: 117g for 11-28T size
- ...and 7 more
The reviewer does not mention the 'Ultralight SPEDAO SLR2 Road Cassette' at any point in the video. The entire transcript is dedicated to analyzing lightweight cassettes from the brand ZTTO, specifically their 'SLR Gen 3' model and other generations. The reviewer discusses a specific failure of a ZTTO cassette, analyzes its design, compares different sizes, and discusses alternatives like the ZTTO SLR Gen 2 and steel cassettes from ZTTO. The brand SPEDAO is not referenced.
aliexpress.comAffiliate by Tom Bowers Cyclingaliexpress.comAffiliate by MyBikePartsThe reviewer analyzes the ZTTO SLR Gen3 11-speed cassette, focusing on a specific failure where the top two sprockets sheared off. They note the cassette is lightweight, visually appealing, and affordable. The design involves the top three sprockets milled from a single aluminum block with the rest being steel. The reviewer has used smaller versions (11-28T) for years without issue, but identifies a design flaw in larger sizes (11-30T and up) where the top two sprockets are connected by a thin ring of supports, creating a potential cantilever beam effect and stress risers. They attribute the specific failure to use on a rough cyclocross course with spiky power delivery. The reviewer concludes that these cassettes prioritize weight savings over durability and safety margin, advising caution with larger sizes.
Pros
- Great looking
- Incredibly lightweight (e.g., 117g for 11-28T vs. 260g for Shimano 105)
- Affordable (about 60 quid)
- ...and 1 more
Cons
- Design flaw in larger sizes (11-30T, 11-32T, 11-34T, 11-36T) where top two sprockets are connected by a thin ring of supports, creating a weak point
- Risk of sprockets shearing off, especially under high, spiky loads (e.g., climbing out of saddle on rough terrain)
- Questionable safety margin due to extreme material milling
- ...and 3 more
Key Points
- Brand: ZTTO
- Model: SLR Gen3
- Construction: Top three sprockets milled from a single block of aluminum, the rest is monolock steel

The reviewer analyzes a failure of the ZTTO ULT2 cassette, specifically the 11-36T version, focusing on a design weakness in the top two aluminum sprockets. They explain the structural and use-case factors that likely led to the failure and compare the design across different cassette sizes.
Pros
- Lightweight (ultralight, prioritizes minimal mass)
- Visually appealing with nice colors
- Good value (built to a price point)
- ...and 1 more
Cons
- Potential structural failure point in the top two sprockets of larger sizes (30T, 32T, 34T, 36T)
- Design creates a cantilever beam effect and stress risers
- Less safety margin due to aggressive material removal
- ...and 3 more
Key Points
- The 11-28T version has a different, stronger web structure where only the largest sprocket uses thin support arms.
- Larger versions (11-30T, 32T, 34T, 36T) have a 'double stack layout' for the top two sprockets connected by a thin ring of supports, increasing failure risk.
- Larger sprockets are more flexible and act as longer lever arms, increasing stress.
- ...and 3 more
The reviewer analyzes the ZTTO Ultraight cassette, focusing on a structural failure in the 11-36T version. They explain the design flaw, compare it to the more robust 11-28T version they use, and discuss how use case and sprocket size affect failure risk. They conclude these cassettes prioritize weight over durability.
Pros
- Lightweight (prioritizes minimal mass)
- Visually appealing with colors
- Good value (built to a price point)
- ...and 1 more
Cons
- Potential structural failure in larger sizes (11-34T, 11-36T) due to design
- Sharp internal edges and 90° corners act as stress risers
- Thin support arms create a cantilever beam effect on top sprockets
- ...and 4 more
Key Points
- Failure observed on an 11-36T version used in cyclocross.
- Design differs by size: only the 11-28T version has a safer design where only the largest sprocket uses thin support arms.
- Larger sprockets act as longer lever arms, increasing peel-off forces.

I've been using it for about 6 months, it's light and inflates quite quickly
aliexpress.comAffiliate by MyBikePartsUse this, no issues or limitations that I've found yet, used to pump up 29x2.6 tyres to 30psi, inflates road tyres no problem.

We love new bike tech and follow bike brands extensively. Riding bike can be a very price intensive thing, but it can be made more accessible by saving some money, and spend it on the parts that matter mostly for you. After a couple of thousand kilometers, most buyer can determine the quality themself. Some YouTubers already have a successful history with using cheaper parts from Aliexpress or eBay. To crowdsource those experiences, we've made this site, to seperate the wheat from the chaff. To be honest, there is also a lot of crap or mediocre stuff out there, but at the same time you can find reliable and quality stuff.
