Zero Friction Cycling, run by former policeman Adam Kerin, presents itself as a trusted source for friction-reducing products, but behind the scenes, a lack of engineering knowledge and unverified testing methods raise red flags. Despite requesting sensitive industry data without doing foundational research, Kerin’s approach appears more focused on marketing high-margin products than adhering to rigorous engineering standards. His testing setup is flawed, and the data he presents, particularly in support of ceramic bearings and chain lubricants, lacks scientific backing. Is this the work of an expert or just another slick sales pitch?
A concerned viewer recently reached out to the Hambini YouTube channel, reporting a peculiar failure of a Favero pedal axle. While Favero is widely respected for the precision of their power meters, there’s scant discussion about the quality of their mechanical engineering. In the “Unfortunate F*cker of the Week” segment, featured in Hambini’s Sunday reaming,…

One of my viewers contacted me about an issue he was having with the installation of a set of NTN bearings. He purchased what he believed to be Loctite 641 from an online supplier, this was promptly delivered with a label indicating it to be “high strength”. This is incorrect as high strength Loctite is…
Shimano has recently launched the CUES groupset. This amalgamates 9, 10 and 11-speed options for flat bar bikes. There are rumours this will move to drop bar (ie road/gravel bikes) in the near future.
AbsoluteBLACK (real name LUCID IP SLU registered in Andorra) were destroyed on social media after their claims about ceramic bearings, power savings and watts were questioned. They systematically curated both their own social media accounts and comments on other accounts. They removed large numbers of comments that questioned their aerodynamic and power claims
