$20 vs $60 Carbon Saddle — Is There Really a Difference?

nikinik

The reviewer discusses the ELITAONE saddle as the fourth item in their comparison. They note it has a short-nose geometry with a pressure relief channel, which they found comfortable. However, they heavily criticize its construction quality, citing sharp burrs on the channel, a lack of markings on the rails, and significant flex in both the top plate and rails. They express doubt that the bottom plate is genuine carbon fiber, suspecting it is molded plastic. They conclude it is a disappointment, especially given its price is similar to a much better saddle (the 'mixed' model).

The reviewer discusses a saddle they refer to as the 'San Marco Speed or Espite', which is likely a mispronunciation or misreading of the 'San Marco Aspide'. They analyze it as the second saddle in their comparison of five carbon saddles from AliExpress. They note it has proper branding, which gives them more confidence. The build quality is described as having the seat material glued onto the saddle rim, similar to the first, cheaper saddle, which could be a long-term issue. However, it makes no cracking noises and is described as a lot stiffer in all directions than the first saddle, inspiring more confidence. The comfort is described as pretty similar to the first saddle, being a long-nose design, which the reviewer personally prefers less than short-nose saddles. It has a pressure relief channel. The weight is 118g, and the price was about $25 USD. The reviewer gives it a rating of 2.5 out of 5.

The reviewer provides a detailed analysis of the MIXED Full Carbon Fiber 5D Ultra Pack Light Weight Bike Saddle (referred to as the 'mixed fullcarbon 5D saddle' or 'mixed saddle'). They state it is substantially better than the previous saddles reviewed, with superior build quality, a more substantial feel, and a modern short-nose geometry. The top material is softer and grippier, and the carbon weave is visible on the bottom plate and rails, indicating a full carbon construction. It is very stiff with no flex. The reviewer found it comfortable on a 2.5-hour ride, praising its shape and the larger pressure relief channel. They note the saddle cover is still glued on, which is a cheaper construction method, but overall they are very positive. They rank it highly and explicitly recommend it as a great option.

The reviewer provides a detailed analysis of the Riot 3D printed honeycomb saddle, which they have used extensively. They state it is one of the more high-end saddles on AliExpress. They praise its build quality, highlighting the 3D printed TPU honeycomb top material, which has remained in perfect condition for almost two years. The bottom plate and rails are described as fully carbon, very properly bonded, and extremely stiff with no flex. It features markings on the rails for precise adjustment. The reviewer notes it is a bit heavier than other reviewed saddles at 146g, and that its price has increased to around $59, placing it in the premium AliExpress segment. They conclude it is 'the best of the best' among the options reviewed.

The Best Deal in Cycling? Magene PES 515 Review (With One Catch)

Tom Bowers Cycling

The reviewer tests and reviews the Magene PES515 power meter, which is a spider-based power meter that comes with a PES crankset. They detail the unboxing, installation on a bike with a Shimano groupset, and extensive testing against other power meters. The reviewer notes the initial accuracy was off by 4-5% compared to their reference pedals, but after applying a calibration offset in the app, it showed excellent precision and repeatability. They conclude it is a very affordable option that requires some user calibration to achieve accuracy.

The reviewer mentions using a ZTTO T47 bottom bracket on a bike for about 5-6,000 miles with minimal maintenance in all weathers, and it remains smooth. They note it contains unbranded, no-name bearings, but the internal T47 design provides a more forgiving environment.

The reviewer states that the Arcaris 8848 Climbers Wheelset is his own/in-house brand's product and a major component for reducing the bike's weight. He plans a dedicated video but provides headline stats and some ride characteristics.

The reviewer states that the CRW Works HB01 Integrated Handlebar integrates super nicely with the frame using the standard FSA ACR headset adapter, making it look like a stock part. They mention it is pretty lightweight, though not the lightest in the world, and allows them to get into their aero position.

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.

My favourite AliExpress cassette might have a problem…

Trace Velo

The 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.
