It's two months now since I started trying a new way of lubing the chain. It's called Squirt "dry lube" and consists of some sort of wax based product that efficiently lubes the chain and, that's the big deal, keeps the chain free from that gritty stuff that gets in there and thrives. My first guinea pig was the Romani and after riding it through some dirt trails things seemed to be running well enough. I don't mean the chain was spic'n'spat -perhaps a bit goopy but not more than a fresh chain- and it kept substantially clean. The test results encouraged me to make a second attempt this time with my trusty randonneuse. Same thing: the chain stays clean of the usual oily mess that sticks into the chain-plates. It also runs smoothly and I've found no difference in shifting (I'm on friction shifters, mind it!). The only thing that still remains a mystery is how long will it take before calling for a relube
If you want to make a try thoroughly follow the maker's specifications. Fully delube the chain first (oil and wax don't match). I used kerosene in my fixie and a standard chain-bath degreaser on the Kogswell.
