Tried many a lube over the years :facepalm: but I don't get on with Wax type stuff, I get that its great at not attracting dirt/dust/sand but for me it's always Wet lubes (applied correctly - wipe off the excess on the external plates) that are the best and just clean them when they get mucky. I can honestly say that my XTR M950
lightly used drivetrain with a fresh chain and wet lube is THE slickest shifting gears I've ever used.
I use Finish Line Dry or Epic Ride if the conditions aren't too nasty.. I did experiment with Wax Lube a few years back but it was a bit of a nightmare, as it kept throwing itself onto the frame/wheels and then drying as hardened white cack. It might have been my lubing technique letting me down though (ahem).
For the cargo bike (which also gets thrashed along a muddy canal path all winter) I discovered Decathlon do a half decent all weather lube which is cheap as chips! Very useful if you have two and a half chains to oil
I've been using Tri-flow for donkey years. I think I used Sim's Tenacious Oil in the early days, but I don't see it sold much. I tried white lightning dry lube and hated it - particularly in the winter. I'm a dyed in the wool wet lube man.
