Scottoilers are horrible things, chain is well lubricated but oil and shite sprayed everywhere else.
Scottoilers are brilliant, but yes can be messy, but then chain drives are messy.
I would do 30,000 miles on a DID ZVM and I couldn’t find any measurable wear on the chain. I never adjusted it between tyre changes. I only ditched them at over 30,000 miles because I was wary of running a third front sprocket on the same chain.
Anyway I’m currently running a R1250R, so no chain to lube, and yeah I do notice how clean the rear of the bike is.
So, back to bicycles. Used various lubes on my emtb. Tried a few wet lubes but came to the conclusion that they just attract dirt and form a grinding paste.
Any bottle of drip on dry wax does me. Currently using a bottle of that Squirt stuff.
