Although it might look like chain waxing is a lot of trouble, it simpler than using wet lube ... in my opinion anyway.
Yes, initial cleaning and setup is a lot of work. The chain has to be cleaned to the bare metal and one needs to buy a crock pot and paraffin.
In an attempt to improve the chain skipping situation, I have removed the chain from the bike yesterday and worked every roller by hand to make sure it rolls freely. Took me good half of hour. But the chain is not stiff anymore. Didn't have time to do a test ride yet. Will report back if the skipping is reduced.
So how much time and hassle is wax lube again?
