Can I use wax on my chain if I ride in extremely cold temperatures without compromising the chains performance and longevity, and if so, what type of wax is best suited for this purpose, or are there other chain lube options that are more effective and reliable in sub-zero conditions? Some argue that wax-based chain lubes are not suitable for cold weather riding as they can freeze and lose their lubricating properties, while others claim that certain types of wax can actually provide better protection and performance in these conditions. What are the pros and cons of using wax-based chain lubes in extremely cold temperatures, and are there any alternative chain lube options that can provide better performance and reliability in these conditions?
