Wax Temperature Debate - Silca Responds!

Summary

Key Points

• Silca claims their testing shows removing a chain from wax at 75°C provides a 1.5-hour longer peak efficiency lifespan compared to 100°C, presenting it as a free way to add longevity. 1:49
• Silca's earlier blog post noted more wax weight on chains removed at cooler temperatures but lacked data to prove a performance impact, suggesting their current testing is recent and needs to be published. 4:50
• The speaker challenges this claim, citing basic physics that high pressure loads during chain break-in will always press out excess wax, regardless of initial removal temperature, leading to the same final wax thickness. 8:55
• The speaker's own testing, including weighing chains before and after break-in and tracking wear rates, showed no significant difference in retained wax or wear between chains removed at 65°C and 100°C. 10:43
• Anecdotal evidence from 15 years and over 150,000 km of personal waxing, including observing no differential wear between chain sections with varying initial wax retention, further contradicts Silca's claim. 18:53
• For users without temperature-controlled pots, adhering to the 75°C removal temperature adds significant time and hassle, potentially discouraging frequent re-waxing, which can lead to higher chain wear. 25:21
• to substantiate their claims and allow for scientific review. 27:54
• The "free" tip of cooler wax removal incurs real costs for users, including increased wax consumption, a longer and messier break-in period, difficulty connecting master links, and potential wax buildup on cogs. 29:40
• The ultimate goal is to provide accurate, evidence-based information to cyclists, preventing unnecessary effort and potential negative outcomes from following unsubstantiated tips. 32:30
• Independent testing is being pursued with Bike Engineering, and other wax manufacturers like Molten Speedwax have already stated they found no benefit to cooler temperature removal. 33:32
• The speaker urges Silca to publish their detailed testing data and methodology, including a clear definition of "peak efficiency 35:53
