Putoline
In terms of performance and durability (and probably chain life) I do believe Putoline is best, but I never knew when it would finally wear off which meant finishing more than one ride with a dry squeaky chain. I guess if I bothered tracking mileages better this wouldn’t have been an issue.
Fenwicks Professional – the grey one with the cowpat aroma.
Fenwick’s seemed almost as good as Putoline and was easier to ‘top up’ so I never had a chain go dry mid-ride.
Viking Juice
I recently washed all the Fenwick’s out of my chain and switched to Juice Lubes, idea being that I wanted something lighter for winter CX and mud so I could rinse off and re-apply every ride. After 3 applications on the stand I went out for an hours ride, but the drivetrain felt like death! Turns out the Fenwicks had been masking the fact that the chain was worn well beyond 1%, and washing it all out and replacing with a thinner lube just exposed this.
So, back to thicker lubes for me! Putoline for now and I’ll just run chain through a rag soaked in Vkkkng Juice after any wet ride.
