I'm guessing Velo was low low on chain oil advert$ so no prob dissing the 'industry' |

so why add wax ? wax is inferior to cebum...why not cook in synth gear lube ? It's misleading to ask why I "add" wax. Wax is the primary component of what goes on my chain. What I "add" is perhaps 10% or less of some other oily substance (gear lube, I think). So a better phrasing is "So why do you use wax?" The answer is because it keeps the chain, the bike, and my pants far cleaner than any of the many oily chain lubes I tried in the past. It gives suitably long chain and sprocket life, according to my experience and at least according to one real-world test. Using my method, it takes less time than carefully applying oil PLUS cleaning the oily grime off the bike. It works best for me. But you use what you like, of course. I'm not trying to change anyone's religion. - Frank Krygowski |
