Hello TJ.
You ready? 😉
I've just reverted to, uh, Finish Line Green wet lube.
I've used Putoline and also Squirt and I think they perform very similarly in terms of longevity and resistance to wet and mud.
Putoline is by far the cheaper of the two but is a faff to apply, Squirt is easier and more expensive.
However, being a huge chain and tyre nerd, I've seen the rate of wear accelerate over the last few months of using squirt. Its not a bad rate of wear comparatively, but its just not as good as my previous lube regime. Down my way, after 4 hours of schlcok, I've got rattly rollers. TJ and I have discussed this and he even took some links apart to examine where the lube remained after some use.
What he's found satisfied him that there was still lube in the right internal spaces of the chain, but I've been less convinced.
My reasoning is simple – wax is solid/semi-solid. After a few rotations at high pressure, its going to get pushed out of the way and cannot flow back to continue lubricating the chain. Wet lube can.
There's scant information available on this topic, and even less about microfilms and phase changes under pressure, so I'm quite happy to accept that I could be talking out of my posterior, but, it seems to me that wax keeps the exterior look of a chain looking good, despite what's going on inside. Therefore, I now use my squirt stock every so often to coat the chain so that it sheds mud and dirt easily, but leave lubrication to Wet lube.
YMMV.
Go Putoline, pedros or Squirt for drylubes.
