Summary from the TLDR Web Dev newsletter

An analysis of the web performance of bike manufacturer websites participating in the 2025 Tour de France was done using a proprietary CrRRUX score based on Core Web Vitals. Merida, Factor, and Giant were the fastest, while Ridley, Orbea, and Trek ranked the slowest, showing a disconnect between brand prestige and website speed. The analysis also went into the technical aspects of each site, highlighting issues like render-blocking resources, client-side rendering, and unoptimized images.
