Last year I was getting a particularly weird rear wheel problem addressed at the not-so LBS (not so because they are the best shop within 30 miles and I had to drive by several very good shops to get there). After the problem was fixed the shop mechanic handed me a small vial of chain lube (free sample) and said try this, it's really great and is being mixed and sold by a local guy. He says it's a great product and I trust him, He says it stays on the chain and you don't need to relube or clean as often. Hmm - less work, I'm up for that... So I take my wheel home, reassemble the bike and through the vial in the miscellaneous bike junk box and forget about it - I am an avid finish line user.
For Christmas my older daughter buys me a new Record chain (I raise them right), so as I am getting the bike tuned up I decide it's time to change the chain out. After that's done I look for the tube of finish line and find it's just about empty and then I remember this vial. Hmmm, new chain - time to test a new product. I put the stuff on, it smells like 90W gear oil and has the same consistency. If goes on clean and easy.
Here's the thing, about 3 weeks of riding, about 200 miles with no reoiling - the chain and rear cassette are still pretty clean, no dull black look that I usually see after a few long rides), no grimy buildup in the spiders. The drive train is still smooth (I can usually tell by feel if it needs a cleaning or lubing). The bike does need a good wash down after a few morning rides on wet roads. Now I know a new chain has a dense film of lube on it, but that does not last too long, this stuff - what ever it is it seems to work pretty well. I have enough for one more application and will try it after I clean the bike again, if that seems to work well too I think I will switch. I may even try some Hypoid (90W) - I think I still have a bottle from when I use to work on cars. Stuff stinks but if it works better, who cares.
