Bike Chain Efficiency Testing: Wax vs Oils, Old vs New Chains, Singlespeed vs Gears, OSPW

CyclingAbout.com recently published comprehensive testing on bicycle chain efficiency, meticulously comparing various lubrication methods and component choices. Their findings indicate that properly waxed chains consistently outperform wet-lubed alternatives, delivering measurable wattage savings across different conditions. The analysis also highlighted the marginal gains offered by oversized pulley wheel systems (OSPW) and the expected efficiency drop-off in older, stretched chains, reinforcing long-held beliefs within the performance cycling community.

This latest round of testing provides valuable empirical data, extending beyond anecdotal evidence or manufacturer claims. The perennial debate between wax and traditional oil lubricants has long been a hot topic among performance-oriented riders and triathletes, with many seeking any advantage to be gained. While the wattage savings might appear small in isolation, particularly for the average rider, they become significant for elite athletes, time trialists, and those engaged in long-distance events where cumulative effort dictates outcomes.

Ultimately, the takeaway is clear: if you're chasing every watt, wax remains king, and component maintenance isn't just about longevity, it's about performance. Perhaps the industry will finally shift its focus from flashy marketing to fundamental friction reduction.
