I've been running two bikes with SA 3-speeds for a while now, and I've been oiling the hubs with Finish Line wet Teflon lube. Is this likely to be an issue mechanically? I've regreased all 3 bearings on both with synthetic grease, so I reckon I've avoided any problems with synthetic and mineral lubricants meeting, is there any other issue?

Thanks in advance.

I don't think you will have any issues, but a thicker oil is typically used for that application. I use Phil Wood Tenacious Oil in my old 3-speed hubs.

OK So this may be a really dumb question but I really feel like I`m missing something. Personally I was unaware that Finish Line was making any WET Teflon lube products so I checked their website and was unable to find any there myself.

Could you post a link or name a specific product please?

I'm +1 on the phil tenacious oil. squirted down the indicator chain hole.
I take the cones out and clean and grease the bearings that the wheel rolls on.

They do not make a wet Teflon lube. I think the OP is talking about this: https://www.finishlineusa.com/product...untry-lube.htm

Look at things this way. An IGH hub is most similar functionally to a gearbox or differential on your automobile, though obviously lighter duty. If you look, you won't find a single maker of these products that recommends using teflon. There must be a reason, and though you may not know why, you'd be wise to stay on the well trod path of oiling your hub with oil.

Note also that IGH hubs (like most gear box systems) depend on splash lubrication to circulate the oil as the wheel turns and keep all parts lubed long term. Lubes that dry up do not splash, or circulate will rapidly wear off the mating surfaces leaving then unprotected.

I`m kinda hoping not. Thats intended as a chain lube and the producr description projects a 100 mile effective protection in wet weather. In keeping with that expectancy and in an effort to be environmentally friendly - the prodect has been engineered to be biodegradable.

So if you check the spec sheet - the oil products are expected to undergo a 60% degradation over a 28 day period. I imagine that in a SA hub with less exposure to oxygen you might get more life expectancy - but definately not what I`d want to use anywhere I was gunning for reduced maintenaince.

Also be sure never to use a friction-modified lube in a hub with a coaster brake. You'll get very looooonnnnnggggg stopping distances! Don't even ask - it was many years ago before I knew most everything.

Yeah, that's what it is. It stays wet when it's on my chain, so I figure it does the same inside my hubs.

As an off-topic, it's my favorite chain lube so far.
